Trevor Dupuy on Military Innovation

In an article published by the Association of the U.S. Army last November that I missed on the first go around, U.S. Army Colonel Eric E. Aslakson and Lieutenant Colonel Richard T. Brown, (ret.) make the argument that “Staff colonels are the Army’s innovation center of gravity.”

The U.S. defense community has settled upon innovation as one of the key methods for overcoming the challenges posed by new technologies and strategies adapted by potential adversaries, as articulated in the Third Offset Strategy developed by the late Obama administration. It is becoming clear however, that a desire to innovate is not the same as actual innovation. Aslakson and Brown make the point that innovation is not simply technological development and identify what they believe is a crucial institutional component of military innovation in the U.S. Army.

Innovation is differentiated from other forms of change such as improvisation and adaptation by the scale, scope and impact of that value creation. Innovation is not about a new widget or process, but the decisive value created and the competitive advantage gained when that new widget or process is applied throughout the Army or joint force…

However, none of these inventions or activities can rise to the level of innovation unless there are skilled professionals within the Army who can convert these ideas into competitive advantage across the enterprise. That is the role of a colonel serving in a major command staff leadership assignment…

These leaders do not typically create the change. But they have the necessary institutional and operational expertise and experience, contacts, resources and risk tolerance to manage processes across the entire framework of doctrine, organization, training, materiel, leadership and education, personnel and facilities, converting invention into competitive advantage.

In his seminal book, The Evolution of Weapons and Warfare (Indianapolis, IN: The Bobbs-Merrill Company, Inc., 1980), Trevor Dupuy noted a pattern in the historical relationship between development of weapons of increasing lethality and their incorporation in warfare. He too noted that the crucial factor was not the technology itself, but the organizational approach to using it.

When a radically new weapon appears and is first adopted, it is inherently incongruous with existing weapons and doctrine. This is reflected in a number of ways; uncertainty and hesitation in coordination of the new weapon with earlier ones; inability to use it consistently, effectively, and flexibly in offensive action, which often leads to tactical stalemate; vulnerability of the weapon and of its users to hostile countermeasures; heavy losses incident to the employment of the new weapon, or in attempting to oppose it in combat. From this it is possible to establish the following criteria of assimilation:

  1. Confident employment of the weapon in accordance with a doctrine that assures its coordination with other weapons in a manner compatible with the characteristics of each.
  2. Consistently effective, flexible use of the weapon in offensive warfare, permitting full employment of the advantages of superior leadership and/or superior resources.
  3. Capability of dealing effectively with anticipated and unanticipated countermeasures.
  4. Sharp decline in casualties for those employing the weapon, often combined with a capability for inflicting disproportionately heavy losses on the enemy.

Based on his assessment of this historical pattern, Dupuy derived a set of preconditions necessary for a successful assimilation of new technology into warfare.

  1. An imaginative, knowledgeable leadership focused on military affairs, supported by extensive knowledge of, and competence in, the nature and background of the existing military system.
  2. Effective coordination of the nation’s economic, technological-scientific, and military resources.
    1. There must exist industrial or developmental research institutions, basic research institutions, military staffs and their supporting institutions, together with administrative arrangements for linking these with one another and with top decision-making echelons of government.
    2. These bodies must conduct their research, developmental, and testing activities according to mutually familiar methods so that their personnel can communicate, can be mutually supporting, and can evaluate each other’s results.
    3. The efforts of these institutions—in related matters—must be directed toward a common goal.
  3. Opportunity for battlefield experimentation as a basis for evaluation and analysis.

Does the U.S. defense establishment’s organizational and institutional approach to innovation meet these preconditions? Good question.

More On The U.S. Army’s ‘Identity Crisis’

The new edition of the U.S. Army War College’s quarterly journal Parameters contains additional commentary on the question of whether the Army should be optimizing to wage combined arms maneuver warfare or wide-area security/Security Force Assistance.

Conrad Crane, the chief of historical services at the U.S. Army Heritage and Education Center offers some comments and criticism of an article by Gates Brown, “The Army’s Identity Crisis” in the Winter 2016–17 issue of Parameters. Brown then responds to Crane’s comments.

What Would An Army Optimized For Multi-Domain Battle Look Like?

As the U.S. Army develops its new Multi-Domain Battle (MDB) concept and seeks to modernize and upgrade its forces, some have called for optimizing its force structure for waging combined arms maneuver combat. What would such an Army force structure look like?

The active component of the Army currently consists of three corps, 10 divisions, 16 armored/Stryker brigade combat teams (BCTs), 15 light infantry BCTs, 12 combat aviation brigades, four fires brigades, three battlefield surveillance brigades, one engineer brigade, one Ranger brigade, five Special Forces groups, and a special operations aviation regiment.

U.S. Army Major Nathan A. Jennings and Lt. Col. Douglas Macgregor (ret.) have each proposed alternative force structure concepts designed to maximize the Army’s effectiveness for combined arms combat.

Jennings’s Realignment Model

Jennings’s concept flows directly from the precepts that MDB is being currently developed upon.

Designed to maximize diverse elements of joint, interorganizational and multinational power to create temporary windows of advantage against complex enemy systems, the Army’s incorporation of [MDB] should be accompanied by optimization of its order of battle to excel against integrated fire and maneuver networks.

To that end, he calls for organizing U.S. Army units into three types of divisions: penetration, exploitation and stabilization.

Empowering joint dynamism begins with creating highly mobile and survivable divisions designed to penetrate complex defenses that increasingly challenge aerial access. These “recon-strike” elements would combine armored and Stryker BCTs; special operations forces; engineers; and multifaceted air defense, indirect, joint, cyber, electromagnetic and informational fires to dislocate and disintegrate adversary defenses across theater depth. As argued by Lt. Gen. H.R. McMaster, then-director of the Army Capabilities Integration Center, they could “fight their way through long-range weapons fire and gain physical contact with hard-to-find opponents” while striking “from unexpected directions with multiple forms of firepower.”

Exploitation divisions would employ more balanced capabilities to destroy enemy concentrations, clear contested zones and seize key terrain. Comprising a variety of light, airborne, motorized and mechanized infantry BCTs with modest armor and engineer support—all empowered by destructive kinetic, electronic and virtual fires—these commands would attack through windows of opportunity created by deep strikes to overmatch paralyzed defenders. While penetrating formations would rapidly bridge air and land component efforts, their more versatile and flexible exploitation counterparts would allow joint commands to decisively shatter adversary warfighting capabilities through intensive fire and maneuver.

The third type of division would be made up of elements trained to consolidate gains in order to set the conditions for a sustainable, stable environment, as required by Army doctrine. The command’s multifaceted brigades could include tailored civil affairs, informational, combat advisory, military police, light infantry, aviation and special operations elements in partnership with joint, interdepartmental, non-governmental and coalition personnel. These stabilization divisions would be equipped to independently follow penetration and exploitation forces to secure expanding frontages, manage population and resource disruptions, negotiate political turbulence, and support the re-establishment of legitimate security forces and governance.

Jennings did not specify how these divisions would be organized, how many of each type he would propose, or the mix of non-divisional elements. They are essentially a reorganization of current branch and unit types.

Proposing separate penetration and exploitation forces hearkens back to the earliest concepts of tank warfare in Germany and the Soviet Union, which envisioned infantry divisions creating breaches in enemy defenses, through which armored divisions would be sent to attack rear areas and maneuver at the operational level. Though in Jennings’s construction, the role of infantry and armor would be reversed.

Jennings’s envisioned force also preserves the capability for conducting wide area security operations in the stabilization divisions. However, since the stabilization divisions would likely constitute only a fraction of the overall force, this would be a net reduction in capability, as all of the current general purpose force units are (theoretically) capable of conducting wide area security. Jennings’s penetration and exploitation divisions would presumably possess more limited capability for this mission.

Macgregor’s Transformation Model

While Jenning’s proposed force structure can be seen as evolutionary, Macgregor’s is much more radically innovative. His transformation concept focuses almost exclusively on optimizing U.S. ground forces to wage combined arms maneuver warfare. Macgregor’s ideas stemmed from his experiences in the 1991 Gulf War and he has developed and expanded on them continuously since then. Although predating MDB, Macgregor’s concepts clearly influenced the thinking behind it and are easily compatible with it.

In a 2016 briefing for Senator Tom Cotton, Macgregor proposed the following structure for U.S. Army combat forces.

The heart of Macgregor’s proposal are modular, independent, all arms/all effects, brigade-sized combat groups that emphasize four primary capabilities: maneuver (mobile armored firepower for positional advantage), strike (stand-off attack systems), ISR (intelligence, surveillance, reconnaissance) and sustainment (logistics). These modular groups would be the Army’s contribution to cross-domain, corps-level joint task forces, which is how he—and increasingly the rest of the U.S. armed forces—sees the U.S. military waging combat in the future.

Macgregor’s envisioned force structure adds his Reconnaissance Strike Group (RSG) to armored, mechanized infantry, and airborne/air-assault light infantry units. These would total 26 brigade-sized groups, down from the current 31 BCTs, with a ratio of 16 RSG/armored groups to 10 mechanized/airborne infantry.

Macgregor would also downsize the number of manned rotary wing combat aviation elements from 12 to four mostly be replacing them with drones integrated into the independent strike groups and into the strike battalions in the maneuver groups.

He would add other new unit types as well, including theater missile defense groups, C41I groups, and chem-bio warfare groups.

Macgregor’s proposed force structure would also constitute a net savings in overall manpower, mainly by cutting out division-level headquarters and pushing sustainment elements down to the individual groups.

Evolution or Revolution?

While both propose significant changes from the current organization, Jennings’s model is more conservative than Macgregor’s. Jennings would keep the division and BCT as the primary operational units, while Macgregor would cut and replace them altogether. Jennings clearly was influenced by Macgregor’s “strike-reconnaissance” concept in his proposal for penetration divisions. His description of them is very close to the way Macgregor defines his RSGs.

The biggest difference is that Jennings’s force would still retain some capacity to conduct wide area security operations, whether it be in conventional or irregular warfare circumstances. Macgregor has been vocal about his belief that the U.S. should avoid large-scale counterinsurgency or stabilization commitments as a matter of policy. He has also called into question the survivability of light infantry on future combined arms battlefields.

Even should the U.S. commit itself to optimizing its force structure for MDB, it is unclear at this point whether it would look like what Jennings or Macgregor propose. Like most military organizations, the U.S. Army is not known for its willingness to adopt radical change. The future Army force structure is likely to resemble its current form for some time, unless the harsh teachings of future combat experience dictate otherwise.

The U.S. Army’s Identity Crisis: Optimizing For Future Warfare

[GlobalSecurity.org]

As the U.S. national security establishment grapples with the implications of the changing character of warfare in the early 21st century, one of more difficult questions to be addressed will be how to properly structure its land combat forces. After nearly two decades of irregular warfare, advocates argue that U.S land forces are in need of recapitalization and modernization. Their major weapons systems are aging and the most recent initiative to replace them was cancelled in 2009. While some upgrades have been funded on the margins, U.S. Army and U.S. Marine Corps leaders have also committed to developing a new warfighting doctrine—Multi-Domain Battle (MDB)—to meet the potential challenges of 21st century warfare.

Because conflicts arising from Great Power rivalries and emerging regional challenges pose the greatest potential strategic danger to the U.S., some have called for optimizing the Army to execute combined arms maneuver warfare against peer or near-peer armies. Recent experience suggests however that the most likely future conflicts the U.S. will engage in will involve ongoing post-Cold War ethnic and nationalist-driven political violence, leading others to support a balanced force structure also capable of conducting wide-area security, or stabilization operations and counterinsurgency.

The Army attempted in 2011 to define wide-area security and combined arms maneuver as the two core competencies in its basic doctrine that would allow it to best prepare for these contingencies. By 2016, Army doctrine abandoned specific competencies in favor of the ability to execute “unified land operations,” broadly defined as “simultaneous offensive, defensive, and stability or defense support of civil authorities tasks to seize, retain, and exploit the initiative and consolidate gains to prevent conflict, shape the operational environment, and win our Nation’s wars as part of unified action.”

The failure to prioritize strategic missions or adequately fund modernization leaves the Army in the position of having to be ready to face all possible contingencies. Gates Brown claims this is inflicting an identity crisis on the Army that jeopardizes its combat effectiveness.

[B]y training forces for all types of wars it ends up lessening combat effectiveness across the entire spectrum. Instead of preparing inadequately for every war, the Army needs to focus on a specific skill set and hone it to a sharp edge… [A] well-defined Army can scramble to remedy known deficiencies in combat operations; however, consciously choosing not to set a deliberate course will not serve the Army well.

The Army’s Identity Crisis

To this point, the Army has relied on a balanced mix of land combat forces divided between armor (heavy tracked and medium wheeled) and light infantry formations. Although optimized for neither combined arms maneuver nor wide-area security, these general purpose forces have heretofore demonstrated the capability to execute both missions tolerably well. The Active Army currently fields 10 divisions comprising 31 Brigade Combat Teams (BCTs) almost evenly split between armor/mechanized and infantry (16 armored/Stryker and 15 infantry).

Major Nathan Jennings contends that the Army force structure should be specifically reorganized for combined arms maneuver and MDB.

Designed to maximize diverse elements of joint, interorganizational and multinational power to create temporary windows of advantage against complex enemy systems, the Army’s incorporation of the idea should be accompanied by optimization of its order of battle to excel against integrated fire and maneuver networks. To that end, it should functionalize its tactical forces to fight as penetration, exploitation and stabilization divisions with corresponding expertise in enabling the vast panoply of American and allied coercive abilities.

This forcewide realignment would enable “flexible and resilient ground formations [to] project combat power from land into other domains to enable joint force freedom of action,” as required by Gen. David G. Perkins, commander of the U.S. Army Training and Doctrine Command. While tailored brigades and battalions would feature combined arms with the ability to maneuver in a dispersed manner, optimized divisions would allow functional expertise in rear, close, deep and non-linear contests while maintaining operational tempo throughout rapid deep attacks, decisive assaults, and consolidation of gains. The new order would also bridge tactical and operational divides to allow greater cross-domain integration across the full range of military operations.

On the other hand, Lieutenant Colonel Jason Nicholson advocates heeding the lessons of the last decade and a half of U.S. experience with irregular warfare and fielding an upgraded, yet balanced, force structure. He does not offer a prescription for a proper force mix, but sees the recent Army decision to stand up six Security Force Assistance Brigades (SFABs) as an encouraging development.

The last sixteen years of ongoing military operations have been conducted at the expense of future requirements of all types. The modernization problems presented by “small wars” challenge the Army as surely as those related to high-intensity conflicts. While SFABs are a step in the right direction, greater investment is required to maximize the lessons learned after sixteen years of counterinsurgency. Training for specific missions like combat advising and security force assistance should be institutionalized for tactical units beyond the designated SFABs. The need for additional capabilities for operating in austere environments will also drive equipment requirements such as lighter power generation and enhanced tactical mobility. Greater expeditionary logistics, armor, and fire support assets will also be critical in future operations. Hybrid warfare, from the Russian campaign in Ukraine to the French campaign in Mali, will continue to change the nature of “small wars.” Megacities, climate change, and other similar challenges will require the same attention to detail by the Army as near-peer conflict in order to ensure future operational success.

No Simple Answers To Strategic Insolvency

Decisions regarding the Army’s force structure will be in the hands of senior political and military decision-makers and will require hard choices and accepting risks. Proponents of optimizing for combined arms maneuver concede that future U.S. commitments to counterinsurgency or large-scale stabilization operations would likely have to be curtailed. Conversely, a balanced force structure is a gamble that either conventional war is unlikely to occur or that general purpose forces are still effective enough to prevail in an emergency.

Hal Brands and Eric Edelman argue that the U.S. currently faces a crisis of “strategic insolvency” due to the misalignment of military capabilities with geopolitical ends in foreign policy, caused by the growth in strategic and geopolitical challenges combined with a “disinvestment” in defense resources. They contend that Great Powers have traditionally restored strategic solvency in three ways:

  • “First, they can decrease commitments thereby restoring equilibrium with diminished resources.”
  • “Second, they can live with greater risk by gambling that their enemies will not test vulnerable commitments or by employing riskier approaches—such as nuclear escalation—to sustain commitments on the cheap.”
  • “Third, they can expand capabilities, thereby restoring strategic solvency.”

Brands and Edelman contend that most commentators favor decreasing foreign policy commitments. Thus far, the U.S. has seemingly adopted the second option–living with greater risk—by default, simply by avoiding choosing to reduce foreign policy commitments or to boost defense spending.

The administration of President Donald Trump is discovering, however, that simply choosing one course over another can be politically problematic. On the campaign trail in 2016, Trump called for expanding U.S. military capability, including increasing U.S. Army end strength to 540,000, rebuilding the U.S. Navy to at least 350 vessels, adding 100 fighter and attack aircraft to boost the U.S. Air Force to 1,200 aircraft, and boosting the U.S. Marine Corps from 24 battalions to 36. He signed an executive order after assuming office mandating this expansion, stating that his administration will pursue an as-yet undefined policy of “peace through strength.”

Estimates for the cost of these additional capabilities range from $55-$95 billion in additional annual defense spending. Trump called for an additional $54 billion spending on defense in his FY 2018 budget proposal. Secretary of Defense James Mattis told members of Congress that while the additional spending will help remedy short-term readiness challenges, it is not enough to finance the armed services plans for expansion and modernization. As Congress wrangles over a funding bill, many remain skeptical of increased government spending and it is unclear whether even Trump’s proposed increase will be approved.

Trump also said during the campaign that as president, he would end U.S. efforts at nation-building, focusing instead on “foreign policy realism” dedicated to destroying extremist organizations in conjunction with temporary coalitions of willing allies regardless of ideological or strategic differences. However, Trump has expressed ambivalent positions on intervention in Syria. While he has stated that he would not deploy large numbers of U.S. troops there, he also suggested that the U.S. could establish “safe zones” His cabinet has reportedly debated plans to deploy up to tens of thousands of ground troops in Syria in order to clear the Islamic State out, protect local populations, and encourage the return of refugees.

It does not appear as if the Army’s identity crisis will be resolved any time soon. If the past is any indication, the U.S. will continue to “muddle through” on its foreign policy, despite the risks.

 

Army University Press “The Future of War” Resource

Army University Press has created a new web resource, New Extended Battlefield: Future of War. Its main focus is on the current Multi-Domain Battle concept under development by the U.S. Army and U.S. Marine Corps. The site contains links to other sites addressing relevant topics, articles and papers on MDB, and relevant news items and current events.

On the front page, the site links to an article written in 1981 by General Donn A. Starry, one of the prime movers behind the development of the Army’s AirLand Battle doctrine. His notion of the “extended battlefield” remains as relevant today as when he first addressed it.

Its definitely worth checking out.

A New-Style Army Brigade For Multi-Domain Battle

Schematic depiction of Douglas Macgregor’s proposed Reconnaissance Strike Group (RSG). Douglas Macgregor, PhD, “Information Briefing on the Reconnaissance Strike Group (RSG) as presented in the FY 17 National Defense Authorization Bill,” 31 October 2016

As the U.S. Army and Marine Corps work together to define multi-domain battle, their joint concept for waging warfare in the near future, will they redesign their force structures? This seems possible for the Army at least; Congress has already ordered it to evaluate proposed changes. In the context of the ongoing debate over U.S. Army readiness, Daniel L. Davis, a Senior Fellow for Defense Priorities at The National Interest, highlights one idea whose time may have come: the Reconnaissance Strike Group (RSG).

The RSG concept is the brainchild of Douglas Macgregor (LTC, U.S. Army, retired), a Gulf War combat veteran, military thinker, and author who has acquired a reputation as a gadfly for his forceful critiques of U.S. land warfare doctrine and recent combat operations. Macgregor has been an outspoken advocate since the 1990s for reorganizing the Army to fully exploit the advantages promised by the Revolution in Military Affairs and maneuver warfare.

Congress Gets Involved

Macgregor’s arguments have received renewed attention following sobering assessments of the implications of Russia’s successful military operations in the Ukraine. He gained a powerful patron after briefing Senator John McCain, chairman of the Senate Armed Services Committee, in January 2015. McCain subsequently arranged for Macgregor to brief other senators and Congressional staff on his assessments of relative U.S. and Russian military capabilities as well as the RSG concept.

In January 2016, the National Commission on the Future of the Army, created by the 2015 National Defense Authorization Act, recommended that Congress mandate that the Army assess alternative combat force design and operational concepts, including the RSG. Section 1091 of the 2017 National Defense Authorization Act, signed by President Barack Obama in October 2016, directed the Chairman of the Joint Chiefs of Staff and the Chief of Staff of the Army to separately report on “alternative Army operational concepts and organizational designs, known as the Reconnaissance Strike Group.” (It is not clear from this wording if this applies only to the RSG or to other concepts and designs as well.)

In consultation with the United States European Command commander, the JCS Chairman and Army Chief of Staff are each to appraise operational merits, feasible force mix under programmed end-strength, estimated costs for assessed potential force structure changes, and strategic force sufficiency and risks. Their findings are then to be each independently reviewed and evaluated by a Federally Funded Research and Development Center of their choice. The final reports, independent reviews, and JCS Chairman and Army Chief of Staff recommendations are to be submitted to the Senate and House armed services committees no later than October 2017.

The RSG and Multi-Domain Battle

Since the passage of the 2017 NDAA, the Army has publicly unveiled its multi-domain battle operational concept and committed to developing it in conjunction with the Marine Corps. What impact this may have on the RSG concept evaluation is not clear. On the face of it, the RSG appears tailor-made for multi-domain battle. However, while Macgregor was lobbying on its behalf in 2015, LTG H. R. McMaster, then commander of the U.S. Army’s Capabilities Integration Center (now currently the Assistant to the President for National Security Affairs) was reported to be a skeptic. McMaster appeared to disagree with Macgregor’s assertions that the current Army Brigade Combat Team structures were too heavy and ponderous to fight effectively in hybrid warfare environments. He suggested that Macgregor’s proposed RSGs were insufficiently manned to conduct vitally important stabilization operations and were too lightly supported logistically.

These disagreements were likely more apparent than real. McMaster’s subsequent emphasis on cross-domain fires as one solution to the challenges of Russian military capabilities and anti-access/area denial environments sound strikingly similar to Macgregor’s “all arms/all effects” RSG concepts. The capabilities Macgregor advocates and claims for the RSG comport very closely to the current conceptualization of multi-domain battle. If the Army does not adopt the RSG, it will probably develop come up with very similar.

That is not to say that multi-domain battle and the RSG do not face some serious opposition within the Army. The changes they portend will have serious repercussions on the armor and airborne branches and more traditional warfighting concepts. I will take a closer look at the RSG concept and its possible implications in my next post.

DOD Successfully Tests Micro-Drones

The Defense Department announced yesterday a successful test of the world’s largest micro-drone swarm. Conducted at China Lake, California in October 2016 by the DOD’s Strategic Capabilities Office, in partnership with Naval Air Systems Command, three F/A-18 Super Hornets launched 103 Perdix micro-drones. According to the DOD press release, “the micro-drones demonstrated advanced swarm behaviors such as collective decision-making, adaptive formation flying, and self-healing.”

The micro-drone swarm comprises an autonomous system.

“Due to the complex nature of combat, Perdix are not pre-programmed synchronized individuals, they are a collective organism, sharing one distributed brain for decision-making and adapting to each other like swarms in nature,” said [Strategic Capabilities Office] Director William Roper. “Because every Perdix communicates and collaborates with every other Perdix, the swarm has no leader and can gracefully adapt to drones entering or exiting the team.”

The Perdix micro-drones were originally designed by Massachusetts Institute of Technology engineering students, and modified for military use by the MIT Lincoln Laboratory in 2013.

To get an idea of the military potential of this technology, watch the demo video tracking the simulated mission.

In related news, the U.S. Army Research Laboratory and Georgia Technical Institute is developing the capability for soldiers in the field to 3D-print swarms of mini-drones to specific specifications within 24 hours. As reported by Defense One,

“A soldier with a mission need uses a computer terminal to rapidly design a suitable [drone],” says a poster by project chief engineer Zacarhy Fisher. “That design is then manufactured using automated processes such as laser cutting and 3D printing. The solution is sent back to the soldier and is deployed.”

Inspired by the modular adaptability of Legos, Fisher says the each drone could be fabricated in less than a day, with total turnaround time of less than three days.

What Is The Relationship Between Rate of Fire and Military Effectiveness?

marine-firing-m240Over at his Best Defense blog, Tom Ricks recently posed an interesting question: Is rate of fire no longer a key metric in assessing military effectiveness?

Rate of fire doesn’t seem to be important in today’s militaries. I mean, everyone can go “full auto.” Rather, the problem seems to me firing too much and running out of ammunition.

I wonder if this affects how contemporary military historians look at the tactical level of war. Throughout most of history, the problem, it seems to me, was how many rocks, spears, arrows or bullets you could get off. Hence the importance of drill, which was designed to increase the volume of infantry fire (and to reduce people walking off the battlefield when they moved back to reload).

There are several ways to address this question from a historical perspective, but one place to start is to look at how rate of fire relates historically to combat.

Rate of fire is one of several measures of a weapon’s ability to inflict damage, i.e. its lethality. In the early 1960s, Trevor Dupuy and his associates at the Historical Evaluation Research Organization (HERO) assessed whether historical trends in increasing weapon lethality were changing the nature of combat. To measure this, they developed a methodology for scoring the inherent lethality of a given weapon, the Theoretical Lethality Index (TLI). TLI is the product of five factors:

  • rate of fire
  • targets per strike
  • range factor
  • accuracy
  • reliability

In the TLI methodology, rate of fire is defined as the number of effective strikes a weapon can deliver under ideal conditions in increments of one hour, and assumes no logistical limitation.

As measured by TLI, increased rates of fire do indeed increase weapon lethality. The TLI of an early 20th century semi-automatic rifle is nearly five times higher than a mid-19th century muzzle-loaded rifle due to its higher rate of fire. Despite having lower accuracy and reliability, a World War II-era machine gun has 10 times the TLI of a semi-automatic rifle due to its rate of fire. The rate of fire of small arms has not increased since the early-to-mid 20th century, and the assault rifle, adopted by modern armies following World War II, remains that standard infantry weapon in the early 21st century.

attrition-fig-11

Rate of fire is just but one of many factors that can influence a weapon’s lethality, however. Artillery has much higher TLI values than small arms despite lower rates of fire. This is for the obvious reasons that artillery has far greater range than small arms and because each round of ammunition can hit multiple targets per strike.

There are other methods for scoring weapon lethality but the TLI provides a logical and consistent methodology for comparing weapons to each other. Through the TLI, Dupuy substantiated the observation that indeed, weapons have become more lethal over time, particularly in the last century.

But if weapons have become more lethal, has combat become bloodier? No. Dupuy and his colleagues also discovered that, counterintuitively, the average casualty rates in land combat have been declining since the 17th century. Combat casualty rates did climb in the early and mid-19th century, but fell again precipitously from the later 19th century through the end of the 20th.

attrition-fig-13

The reason, Dupuy determined, was because armies have historically adapted to increases in weapon lethality by dispersing in greater depth on the battlefield, decentralizing tactical decision-making and enhancing mobility, and placing a greater emphasis on combined arms tactics. The area occupied by 100,000 soldiers increased 4,000 times between antiquity and the late 20th century. Average ground force dispersion increased by a third between World War II and the 1973 Yom Kippur War, and he estimated it had increased by another quarter by 1990.

attrition-fig-14

Simply put, even as weapons become more deadly, there are fewer targets on the battlefield for them to hit. Through the mid-19th century, the combination of low rates of fire and relatively shorter range required the massing of infantry fires in order to achieve lethal effect. Before 1850, artillery caused more battlefield casualties than infantry small arms. This ratio changed due to the increased rates of fire and range of rifled and breach loading weapons introduced in the 1850s and 1860s. The majority of combat casualties in  conflicts of the mid-to-late 19th century were inflicted by infantry small arms.

attrition-fig-19The lethality of modern small arms combined with machine guns led to further dispersion and the decentralization of tactical decision-making in early 20th century warfare. The increased destructiveness of artillery, due to improved range and more powerful ammunition, coupled with the invention of the field telephone and indirect fire techniques during World War I, restored the long arm to its role as king of the battlefield.

attrition-fig-35

Dupuy represented this historical relationship between lethality and dispersion on the battlefield by applying a dispersion factor to TLI values to obtain what he termed the Operational Lethality Index (OLI). By accounting for these effects, OLI values are a good theoretical approximation of relative weapon effectiveness.

npw-fig-2-5Although little empirical research has been done on this question, it seems logical that the trend toward greater use of precision-guided weapons is at least a partial response to the so-called “empty battlefield.” The developers of the Third Offset Strategy postulated that the emphasis on developing precision weaponry by the U.S. in the 1970s was a calculated response to offset the Soviet emphasis on mass firepower (i.e. the “second offset”). The goal of modern precision weapons is “one shot, one kill,” where a reduced rate of fire is compensated for by greater range and accuracy. Such weapons have become sufficiently lethal that the best way to survive on a modern battlefield is to not be seen.

At least, that was the conventional wisdom until recently. The U.S. Army in particular is watching how the Ukrainian separatist forces and their Russian enablers are making use of new artillery weapons, drone and information technology, and tactics to engage targets with mass fires. Some critics have alleged that the U.S. artillery arm has atrophied during the Global War on Terror and may no longer be capable of overmatching potential adversaries. It is not yet clear whether there will be a real competition between mass and precision fires on the battlefields of the near future, but it is possible that it signals yet another shift in the historical relationship between lethality, mobility, and dispersion in combat.

The U.S. armed forces have traditionally excelled in providing fire support for their ground combat maneuver elements, but recent changes have apparently caused concern that this will continue to be the case in the future.

Case in point is the U.S. Army’s Mobile Protected Firepower (MPF) program. The MPF seems to reflect concern by the U.S. Army that future combat environments will inhibit the capabilities of heavy artillery and air support systems tasked with providing fire support for infantry units. As Breaking Defense describes it,

“Our near-peers have sought to catch up with us,” said Fort Benning commander Maj. Gen. Eric Wesley, using Pentagon code for China and Russia. These sophisticated nation-states — and countries buying their hardware, like Iran — are developing so-called Anti-Access/Area Denial (A2/AD): layered defenses of long-range sensors and missiles to keep US airpower and ships at a distance (anti-access), plus anti-tank weapons, mines, and roadside bombs to decimate ground troops who get close (area denial).

The Army’s Maneuver Center of Excellence at Ft. Benning, Georgia is the proponent for development of a new lightly-armored, tracked vehicle mounting a 105mm or 120mm gun. According to the National Interest, the goal of the MPF program is

… to provide a company of vehicles—which the Army adamantly does not want to refer to as light tanks—to brigades from the 82nd Airborne Division or 10th Mountain Division that can provide heavy fire support to those infantry units. The new vehicle, which is scheduled to enter into full-scale engineering and manufacturing development in 2019—with fielding tentatively scheduled for around 2022—would be similar in concept to the M551 Sheridan light tank. The Sheridan used to be operated the Army’s airborne units unit until 1996, but was retired without replacement. (Emphasis added)

As Chris recently pointed out, General Dynamics Land Systems has developed a prototype it calls the Griffin. BAE Systems has also pitched its XM8 Armored Gun System, developed in the 1990s.

The development of a dedicated, direct fire support weapon for line infantry can be seen as something of an anachronism. During World War I, German infantrymen sought alternatives to relying on heavy artillery support that was under the control of higher headquarters and often slow or unresponsive to tactical situations on the battlefield. They developed an expedient called the “infantry gun” (Infanteriegeschütz) by stripping down captured Russian 76.2mm field guns for direct use against enemy infantry, fortifications, and machine guns. Other armies imitated the Germans, but between the wars, the German Army was only one to develop 75mm and 150mm wheeled guns of its own dedicated specifically to infantry combat support.

The Germans were also the first to develop versions mounted on tracked, armored chassis, called “assault guns” (Sturmgeschütz). During World War II, the Germans often pressed their lightly armored assault guns into duty as ersatz tanks to compensate for insufficient numbers of actual tanks. (The apparently irresistible lure to use anything that looks like a tank as a tank also afflicted the World War II U.S. tank destroyer as well, yielding results that dissatisfied all concerned.)

Other armies again copied the Germans during the war, but the assault gun concept was largely abandoned afterward. Both the U.S. and the Soviet Union developed vehicles intended to provide gunfire support for airborne infantry, but these were more aptly described as light tanks. The U.S. Army’s last light tank, the M551 Sheridan, was retired in 1996 and not replaced.

It appears that the development of new technology is leading the U.S. Army back to old ideas. Just don’t call them light tanks.

Are Long-Range Fires Changing The Character of Land Warfare?

Has U.S. land warfighting capability been compromised by advances by potential adversaries in long-range artillery capabilities? Michael Jacobson and Robert H. Scales argue that this is the case in an article on War on the Rocks.

While the U.S. Army has made major advances by incorporating precision into artillery, the ability and opportunity to employ precision are premised on a world of low-intensity conflict. In high-intensity conflict defined by combined-arms maneuver, the employment of artillery based on a precise point on the ground becomes a much more difficult proposition, especially when the enemy commands large formations of moving, armored vehicles, as Russia does. The U.S. joint force has recognized this dilemma and compensates for it by employing superior air forces and deep-strike fires. But Russia has undertaken a comprehensive upgrade of not just its military technology but its doctrine. We should not be surprised that Russia’s goal in this endeavor is to offset U.S. advantages in air superiority and double-down on its traditional advantages in artillery and rocket mass, range, and destructive power.

Jacobson and Scales provide a list of relatively quick fixes they assert would restore U.S. superiority in long-range fires: change policy on the use of cluster munitions; upgrade the U.S. self-propelled howitzer inventory from short-barreled 39 caliber guns to long-barreled 52 calibers and incorporate improved propellants and rocket assistance to double their existing range; reevaluate restrictions on the forthcoming Long Range Precision Fires rocket system in light of Russian attitudes toward the Intermediate Range Nuclear Forces treaty; and rebuild divisional and field artillery units atrophied by a decade of counterinsurgency warfare.

Their assessment echoes similar comments made earlier this year by Lieutenant General H. R. McMaster, director of the U.S. Army’s Capabilities Integration Center. Another option for countering enemy fire artillery capabilities, McMaster suggested, was the employment of “cross-domain fires.” As he explained, “When an Army fires unit arrives somewhere, it should be able to do surface-to-air, surface-to-surface, and shore-to-ship capabilities.

The notion of land-based fire elements engaging more than just other land or counter-air targets has given rise to a concept being called “multi-domain battle.” It’s proponents, Dr. Albert Palazzo of the Australian Army’s War Research Centre, and Lieutenant Colonel David P. McLain III, Chief, Integration and Operations Branch in the Joint and Army Concepts Division of the Army Capabilities Integration Center, argue (also at War on the Rocks) that

While Western forces have embraced jointness, traditional boundaries between land, sea, and air have still defined which service and which capability is tasked with a given mission. Multi-domain battle breaks down the traditional environmental boundaries between domains that have previously limited who does what where. The theater of operations, in this view, is a unitary whole. The most useful capability needs to get the mission no matter what domain it technically comes from. Newly emerging technologies will enable the land force to operate in ways that, in the past, have been limited by the boundaries of its domain. These technologies will give the land force the ability to dominate not just the land but also project power into and across the other domains.

Palazzo and McClain contend that future land warfare forces

…must be designed, equipped, and trained to gain and maintain advantage across all domains and to understand and respond to the requirements of the future operating environment… Multi-domain battle will create options and opportunities for the joint force, while imposing multiple dilemmas on the adversary. Through land-to-sea, land-to-air, land-to-land, land-to-space, and land-to-cyberspace fires and effects, land forces can deter, deny, and defeat the adversary. This will allow the joint commander to seize, retain, and exploit the initiative.

As an example of their concept, Palazzo and McClain cite a combined, joint operation from the Pacific Theater in World War II:

Just after dawn on September 4, 1943, Australian soldiers of the 9th Division came ashore near Lae, Papua in the Australian Army’s first major amphibious operation since Gallipoli. Supporting them were U.S. naval forces from VII Amphibious Force. The next day, the 503rd U.S. Parachute Regiment seized the airfield at Nadzab to the West of Lae, which allowed the follow-on landing of the 7th Australian Division.  The Japanese defenders offered some resistance on the land, token resistance in the air, and no resistance at sea. Terrain was the main obstacle to Lae’s capture.

From the beginning, the allied plan for Lae was a joint one. The allies were able to get their forces across the approaches to the enemy’s position, establish secure points of entry, build up strength, and defeat the enemy because they dominated the three domains of war relevant at the time — land, sea, and air.

The concept of multi-domain warfare seems like a logical conceptualization for integrating land-based weapons of increased range and effect into the sorts of near-term future conflicts envisioned by U.S. policy-makers and defense analysts. It comports fairly seamlessly with the precepts of the Third Offset Strategy.

However, as has been observed with the Third Offset Strategy, this raises questions about the role of long-range fires in conflicts that do not involve near-peer adversaries, such as counterinsurgencies. Is an emphasis on technological determinism reducing the capabilities of land combat units to just what they shoot? Is the ability to take and hold ground an anachronism in anti-access/area-denial environments? Do long-range fires obviate the relationship between fire and maneuver in modern combat tactics? If even infantry squads are equipped with stand-off weapons, what is the future of close quarters combat?
