Multi-Domain Battle And The Maneuver Warfare Debate

The recent commitment by the U.S. Army and Marine Corps to developing the concept of multi-domain battle led me to wonder: is this going to re-ignite the currently-dormant-but-unresolved debate over maneuver vs. attrition in American land warfare thinking? Will long-range precision fires and cross-domain targeting change the relationship between fire and maneuver in modern combat tactics? With an emphasis on fires of the kinetic and non-kinetic variety as the remedy to the challenge of anti-access/area denial capabilities and strategies, are multi-domain warfare theorists swinging the pendulum to the side of attrition?

What Is The Role of Maneuver In Multi-Domain Battle?

Consider this description of the Army’s conception of multi-domain battle offered by General David G. Perkins, Commander, United States Army Training and Doctrine Command:

[F]uture multifunctional Army fires units will provide the joint task force with a single unit combining surface-to-surface (land and maritime), surface-to-air, electromagnetic, and cyberspace cross-domain fires. These fires formations integrate with emerging Navy, Air Force, Marine and special operations forces capabilities to provide the commander multiple resilient options for striking the enemy and covering joint force maneuver.

At the same time, ground forces with improved maneuver and close combat capabilities allow the joint force to overwhelm or infiltrate dispersed enemy formations concealed from joint targeting and fires. A joint force containing effective ground forces requires the enemy to expose their dispersed forces to defeat in ground combat, face destruction from joint fires if they concentrate, or the loss of key terrain if they displace.

Future Army and Marine tactical ground maneuver units will combine sufficient cross-domain fires capability to enable decentralized ground maneuver and the creation of durable domain windows for the joint force with the mobility, lethality and protection to close with and destroy enemy ground forces in close combat. With combined arms pushed to the lowest practical level, these units will be flexible and resilient with the ability to operate in degraded conditions and with sufficient endurance to sustain losses and continue operations for extended periods and across wide areas.

The Army clearly sees maneuver to be an integral part of multi-domain battle, with an emphasis on closing with enemy forces to engage in close combat. However, it seems to me that the same technological changes that are prompting consideration of the new concept raise some questions:

  • What does close combat mean when ground maneuver elements can be brought under devastating surprise long-range precision fire barrages enabled by drone reconnaissance and cyber and information operations long before they close with enemy combat forces?
  • If even infantry squads are equipped with stand-off weapons, what is the future of close quarters combat?
  • Is the ability to take and hold ground an anachronism in anti-access/area-denial environments?
  • Will the purpose of maneuver be to force enemy ground maneuver elements to expose themselves to targeting by long-range precision fires? Or will maneuver mean movement to advantageous long-range precision firing positions, particularly if targeting across domains?
  • Is an emphasis on technological determinism reducing the capabilities of land combat units to just what they shoot?

The Maneuver Warfare Debate

Such questions seem sure to renew debates regarding the relationship between fire and maneuver in U.S. land warfare doctrine. The contemporary concept of maneuver warfare emerged in the early 1980s, as military and civilian practitioners and thinkers in the U.S. and the NATO countries came to grips with the challenges posed by Soviet military power in Europe. Inspired by the tactical and operational successes of the German Army during World War II, William Lind, John Boyd, Robert Leonhard, and Richard Simpkin, among others, drew upon a variety of American, British, German, and even Soviet sources to fashion a concept that established maneuver and attrition as distinct forms of warfare. In this telling, the First World War had been dominated by an overemphasis on the attritional effects of firepower, which yielded only bloody positional stalemate. In response, the Germans innovated new tactics to restore maneuver to the battlefield, which when combined with tanks and aircraft, led to their spectacular “blitzkrieg” victories in World War II. Their adversaries learned and adapted in turn, and developed maneuver doctrines of their own that helped defeat the Germans.

Maneuver warfare theories informed development of the U.S. Army’s AirLand Battle concept and operational doctrine of the late 1980s. The U.S. Marine Corps also integrated maneuver warfare into its doctrine in the 1997 edition of its capstone manual, MCDP-1 Warfighting. The idea of a maneuver style of warfare had plenty of critics, however. By the early 1990s, the Army had settled for a balance between maneuver and firepower in its combat doctrine. Debates and discussions about deep operations persisted into the late 1990s, but were preempted in large measure by the shift to irregular warfare and counterinsurgency after September 11, 2001. U.S. land warfare doctrine did get a brief test during the invasion of Iraq in 2003, but the woefully outclassed Iraq Army was quickly and decisively overwhelmed by American combat power, yielding few insights into future warfare against peer or near-peer opponents.

The last notable public exchange on this topic occurred in 2008 in Small Wars Journal. British defense writer and analyst William F. Owen, argued that a distinction between maneuver and attrition “styles” of warfare was artificial and lacked intellectual rigor and historical support. Eric Walter, a contributor to U.S. Marine Corps doctrinal publications, conceded that existing maneuver warfare theorizing was “fuzzy” in some respects, but countered that the intellectual thinking behind it nevertheless stimulated the U.S. military to sharpen its conception and conduct of warfare. The ensuing discussion thread fleshed out the respective perspectives and the debate continues.

Despite the official enthusiasm of the Army and Marine Corps, there are many aspects of the concept of multi-domain warfare that will need to be worked out if it is to become a viable combat doctrine and not simply justification for development of new weapons. One task will be to overcome the suspicions of the sister services that it is merely a gambit in the ongoing interservice budget battles. (Similar skepticism dogs the associated Third Offset Strategy.) Developing a better sense of exactly how long-range precision fires, cyber and information operations, and other innovative technologies might affect ground combat would be a good place to start.

Logistics in Trevor Dupuy’s Combat Models

Trevor N. Dupuy, Numbers, Predictions and War: Using History to Evaluate Combat Factors and Predict the Outcome of Battles (Indianapolis; New York: The Bobbs-Merrill Co., 1979), p. 79

Mystics & Statistics reader Stiltzkin posed two interesting questions in response to my recent post on the new blog, Logistics in War:

Is there actually a reliable way of calculating logistical demand in correlation to “standing” ration strength/combat/daily strength army size?

Did Dupuy ever focus on logistics in any of his work?

The answer to his first question is, yes, there is. In fact, this has been a standard military staff function since before there were military staffs (Martin van Creveld’s book, Supplying War: Logistics from Wallenstein to Patton (2nd ed.) is an excellent general introduction). Staff officer’s guides and field manuals from various armies from the 19th century to the present are full of useful information on field supply allotments and consumption estimates intended to guide battlefield sustainment. The records of modern armies also contain reams of bureaucratic records documenting logistical functions as they actually occurred. Logistics and supply is a woefully under-studied aspect of warfare, but not because there are no sources upon which to draw.

As to his second question, the answer is also yes. Dupuy addressed logistics in his work in a couple of ways. He included two logistics multipliers in his combat models, one in the calculation for the battlefield effects of weapons, the Operational Lethality Index (OLI), and also as one element of the value for combat effectiveness, which is a multiplier in his combat power formula.

Dupuy considered the impact of logistics on combat to be intangible, however. From his historical study of combat, Dupuy understood that logistics impacted both weapons and combat effectiveness, but in the absence of empirical data, he relied on subject matter expertise to assign it a specific value in his model.

Logistics or supply capability is basic in its importance to combat effectiveness. Yet, as in the case of the leadership, training, and morale factors, it is almost impossible to arrive at an objective numerical assessment of the absolute effectiveness of a military supply system. Consequently, this factor also can be applied only when solid historical data provides a basis for objective evaluation of the relative effectiveness of the opposing supply capabilities.[1]

His approach to this stands in contrast to other philosophies of combat model design, which hold that if a factor cannot be empirically measured, it should not be included in a model. (It is up to the reader to decide if this is a valid approach to modeling real-world phenomena or not.)

Yet, as with many aspects of the historical study of combat, Dupuy and his colleagues at the Historical Evaluation Research Organization (HERO) had taken an initial cut at empirical research on the subject. In the late 1960s and early 1970s, Dupuy and HERO conducted a series of studies for the U.S. Air Force on the historical use of air power in support of ground warfare. One line of inquiry looked at the effects of air interdiction on supply, specifically at Operation STRANGLE, an effort by the U.S. and British air forces to completely block the lines of communication and supply of German ground forces defending Rome in 1944.

Dupuy and HERO dug deeply into Allied and German primary source documentation to extract extensive data on combat strengths and losses, logistical capabilities and capacities, supply requirements, and aircraft sorties and bombing totals. Dupuy proceeded from a historically-based assumption that combat units, using expedients, experience, and training, could operate unimpaired while only receiving up to 65% of their normal supply requirements. If the level of supply dipped below 65%, the deficiency would begin impinging on combat power at a rate proportional to the percentage of loss (i.e., a 60% supply rate would impose a 5% decline, represented as a combat effectiveness multiplier of .95, and so on).

Using this as a baseline, Dupuy and HERO calculated the amount of aerial combat power the Allies needed to apply to impact German combat effectiveness. They determined that Operation STRANGLE was able to reduce German supply capacity to about 41.8% of normal, which yielded a reduction in the combat power of German ground combat forces by an average of 6.8%.

He cautioned that these calculations were “directly relatable only to the German situation as it existed in Italy in late March and early April 1944.” As detailed as the analysis was, Dupuy stated that it “may be an oversimplification of a most complex combination of elements, including road and railway nets, supply levels, distribution of targets, and tonnage on targets. This requires much further exhaustive analysis in order to achieve confidence in this relatively simple relationship of interdiction effort to supply capability.”[2]

The historical work done by Dupuy and HERO on logistics and combat appears unique, but it seems highly relevant. There is no lack of detailed data from which to conduct further inquiries. The only impediment appears to be lack of interest.

Logistics In War

“Amateurs study tactics, armchair generals study strategy, but professionals study logistics,” as the old saw goes. While the veracity of this statement is debatable, there can be little doubt that the study and appreciation of the role of sustainment in warfare lags behind that of the sexier topics of strategy and tactics.  A new blog, Logistics in War, [also on Facebook (https://www.facebook.com/logisticsinwar/) and Twitter (@logisticsinwar)] is seeking to change that.

The anonymous and somewhat mysterious purveyor of the blog bills it as “a public, unofficial, ‘Professional Military Education’ site,” the purpose of which is “to instigate and inspire, continue and create, a discussion on military logistics that is so often sorely lacking (or if it does occur, does so behind closed doors).”

It seems safe to conclude that the blog’s owner is an Australian Army loggie, however: “Although the blog currently reflects an Australian and Army orientation, its vision is to become broadly applicable; to reflect the many different approaches to logistics as practiced by different military Services, the Joint domain, and militaries of all persuasions.”

The initial posts range in subject from a list of suggested readings about logistics, to the impact of sustainment in battle in recent history, to the challenges of supplying combat forces in the multi-domain battle construct. The writing is crisp, clear, and professional, and the questions and topics addressed are of undeniable importance. Logistics in War is a welcome addition to the online conversation about warfare, and is well worth the time to peruse. It will be very interesting to watch it progress and grow.

An Additional Comment on the Link Between Operations, Strategy, and Policy In Russian Hybrid Warfare

A conclusion that Fox alluded to in his article, but did not state explicitly, is that in a sense, the Russians “held back” in the design of their operations against the Ukrainians. It appears quite clear that the force multipliers derived from the battalion tactical groups, drone-enabled recon-strike model, and cyber and information operations capabilities generated more than enough combat power for the Russians to decisively defeat the Ukrainian Army in a larger “blitzkrieg”-style invasion and occupy most, if not all, of the country, if they had chosen to do so.

This clearly is not the desired political goal of the Russian government, however. Instead, the Russian General Staff carefully crafted a military strategy to fulfill more limited political goals, and creatively designed their operations to make full use of their tactical capabilities in support of that strategy.

This successful Clausewitizan calibration of policy, strategy, operations, and tactics by the Russians in Ukraine and Syria should give the U.S. real concern, since itself does not currently seem capable of a similar level of coordination or finesse. Now, the Russian achievements against the relatively hapless Ukrainians, or in Syria, where the ultimate outcome remains very much indeterminate, are no guarantee of future success against more capable and well-resourced opponents. However, it does demonstrate what can be achieved with a relatively weak strategic hand to play through a clear unity of political purpose and military means. This has not been the U.S.’s strong suit historically, and it is unclear at this juncture whether that will change under the incoming Trump administration.

Linking Operations, Strategy, and Policy In Russian Hybrid Warfare

Map depicting the encirclement and withdrawal of Ukrainian forces in the Debaltseve area, 14 January – 20 February 2015 [Map by Goran tek-en (Wikipedia)]

U.S. Army Major Amos Fox, who is quickly establishing himself as one of the brighter sparks analyzing the contemporary Russian way of land warfare, has a new article, “The Russian–Ukrainian War: Understanding the Dust Clouds on the Battlefield,” published by West Point’s Modern War Institute. In it he assesses the linkage between Russian land warfare operations, strategy, and policy.

In Fox’s analysis, despite the decisive advantages afforded to the Russian Army and their Ukrainian Separatist proxies through “the employment of the semi-autonomous battalion tactical group, and a reconnaissance-strike model that tightly couples drones to strike assets, hastening the speed at which overwhelming firepower is available to support tactical commanders,” the actual operations executed by these forces should be characterized as classic sieges, as opposed to decisive operational maneuver.

Fox details three operations employing this approach – tactical combat overmatch enabling envelopment and the subsequent application of steady pressure – that produced military success leading directly to political results advantageous to the Russian government.

According to Fox, the military strategy of siege operations effectively enabled the limited political goals of the Russian government.

What explains Russia’s evident preference for the siege? Would it not make more sense to quickly annihilate the Ukrainians? Perhaps. However, the siege’s benefit is its ability to transfer military power into political progress, while obfuscating the associated costs. A rapid, violent, decisive victory in which hundreds of Ukrainian soldiers are killed in a matter of days is counterproductive to Russia’s political goals, whereas the incremental use of violence over time accomplishes the same objectives with less disturbance to the international community.

Fox believes that this same operational concept was applied by the Syrian Army and its Russian enablers to capture the city of Aleppo last month, albeit with somewhat different tactics, such as substituting airstrikes for long-range artillery and rockets.

He advises that the U.S. would be prudent to plan for and prepare to face the new Russian land warfare capabilities.

These new features of Russian warfare—and an understanding of them in the context of that warfare’s very conventional character—should inform US planning. The contemporary Russian army is combat-experienced in combined arms maneuver at all echelons of command, a skill that the US Army is still working to recover after well over a decade of counterinsurgency operations in Iraq and Afghanistan. This fact could prove troublesome if Russia elects to push further in Europe, infringing upon NATO partners, or if US and Russian interests continue to collide in areas like Syria. Preparing to combat Russian cyber threats or hybrid tactics is important. But the lesson from Ukraine is clear: It is equally vital to train and equip US forces to counter the type of conventional capabilities Russia has demonstrated in Ukraine.

Turkish Army Tanks Proving Vulnerable In Syria

The Turkish Army, conducting Operation EUPHRATES SHIELD in northern Syria since 24 August 2016, has reportedly lost at least 15 German-made, Leopard 2A4 main battle tanks (MBTs) to man-portable anti-tank systems (MANPATs) in combat with Daesh fighters. Five were lost in December 2016 after the Turks deployed several of its 354 Leopard 2A4’s to buttress its offensive, which initially employed mainly older, upgraded American-made M60A3 MBTs. 10 more Leopard 2’s were knocked out in subsequent fighting in urban terrain around the town of al-Bab in northern Syria, 15 miles south of the Turkish-Syrian border.

Daesh fighters have used a variety of anti-tank missiles against the Turkish Army vehicles, including U.S.-made BGM 71 TOW-2s, and Soviet/Russian-produced 9K111 Fagots (“Basoon”) and 9M133 Kornets, all reportedly captured from Syrian and Iraqi Army stocks. The 60-ton Leopard 2, a mainstay of NATO armored forces, earned a reputation for invulnerability after surviving Taliban improvised explosive device (IED) attacks in Afghanistan. However, the A3 version used by the Turks does not have explosive reactive armor or active protection systems, which are used by the many modern MBTs to defeat the new generation of MANPATs.

There is also some evidence that Turkish tank losses are at least partly due to faulty tactical employment. Some of the M60s destroyed in the initial fighting were observed firing from open positions when hit, rather then from less vulnerable hull down locations. The Leopard 2A3’s, with heavy frontal armor, but thinner protection on the sides and rear, were designed for long-range tank v. tank fighting, and are notably unsuited for combat in urban terrain. Successful urban combat places a premium on combined arms tactics, particularly the use of dismounted infantry to clear out potential enemy MANPAT flanking fire positions.

Mosul and ISF Combat Effectiveness

The situation in Mosul, 16-19 December 2016 (Institute for the Study of War)

After a period of “operational refit,” Iraqi Security Forces (ISF) waging battle with Daesh fighters for control of the city of Mosul launched a new phase of their advance on 29 December. The initial phase of the assault, which began on 17 October 2016, ground to a halt due to strong Daesh resistance and heavy casualties among the Iraqi Counterterrorism Service (CTS) troops spearheading the operation.

For the new offensive, the CTS was reinforced with additional Iraqi Army ground units, as well as an armored element of the Federal Police. Additional U.S. combat forces and advisors have also been moved closer to the front lines in support.

Although possessing an enormous manpower advantage over the Daesh defenders, ISF had managed to secure only one-quarter of the city in two months of combat. This is likely due to the fact that the only ISF elements that have demonstrated any offensive combat effectiveness have been the CTS and the Popular Mobilization Forces (PMF, or Hash’d al Shaabi) Iraqi Shi’a militia mobilized by Grand Ayatollah Ali Sistani in 2014. PMF brigades hold the western outskirts of the city, but thus far have been restrained from entering it for fear of provoking sectarian violence with the mostly Sunni residents.

Daesh defenders, believed to number only from 3,000-5,000 at the outset of the battle, have had the luxury of fighting against only one axis of advance and within urban terrain filled with trapped civilians, which they have used as human shields. They mounted a particularly effective counterattack against the CTS using vehicle-borne improvised explosive devices (VBIEDs), which halted the initial offensive in mid-December. ISF casualties appear to be concentrated in the elite 1st Special Operations Brigade (the so-called “Golden Division”) of the CTS. An unnamed Pentagon source was quoted as stating that the Golden Division’s maneuver battalions had incurred “upwards of 50 percent casualties,” which, if sustained, would have rendered it combative ineffective in less than a month.

The Iraqi government has come to rely on the Golden Division to generate reliable offensive combat power. It spearheaded the attacks that recovered Tikrit, Ramadi, and Fallujah earlier in the year. Originally formed in 2004 as the non-sectarian Iraqi Special Operations Forces brigade, the Golden Division was amalgamated into the CTS in 2007 along with specialized counterterrorism and national police elements. Although intended for irregular warfare, the CTS appears to be the only Iraqi military force capable of effective conventional offensive combat operations, likely due to higher level of combat effectiveness relative to the rest of the ISF, as well as its interoperability with U.S. and Coalition supporting forces.

Historically, the Iraqi Army has not demonstrated a high level of overall combat effectiveness. Trevor Dupuy’s analysis of the performance of the various combatants in the 1973 Arab-Israeli War ranked the Iraqi Army behind that of the Israelis, Jordanians, Egyptians, and Syrians. He estimated the Israelis to have a 3.43 to 1.00 combat effectiveness advantage over the Iraqis in 1973. Dupuy credited the Iraqis with improved effectiveness following the 1980-88 Iran-Iraq War in his pre-war estimate of the outcome of the 1990-91 Gulf War. This turned out to be erroneous; overestimation of Iraqi combat effectiveness in part led Dupuy to predict a higher casualty rate for U.S. forces than actually occurred. The ineffective performance of the Iraqi Army in 2003 should have not surprised anyone.

The relative success of the CTS can be seen as either indicative of the general failure of the decade-long U.S. effort to rebuild an effective Iraqi military establishment, or as an exemplary success of the U.S. Special Operations Forces model for training and operating with indigenous military forces. Or both.

Tanks and Russian Hybrid Warfare

tanks-russian-hybrid-warfareU.S. Army Major Amos Fox, currently a student at the U.S. Army Command and General Staff College, has produced an insightful analysis of the role of tanks in Russian hybrid warfare tactics and operations. His recent article in Armor, the journal of the U.S. Army Maneuver Center of Excellence at Ft. Benning, Georgia, offers a sense of the challenges of high-intensity combat on the near-future hybrid warfare battlefield.

Fox assesses current Russia Army tactical and operational capabilities as quite capable.

Russia’s contemporary operations embody the characteristic of surprise. Russian operations in Georgia and Ukraine demonstrate a rapid, decentralized attack seeking to temporally dislocate the enemy, triggering the opposing forces’ defeat. These methods stand in stark contrast to the old Soviet doctrine of methodical, timetable-and echelon-driven employment of ground forces that sought to outmass the opposing army. Current Russian land-warfare tactics are something which most armies, including the U.S. Army, are largely unprepared to address.

Conversely, after achieving limited objectives, Russia quickly transitions to the defense using ground forces, drones and air-defense capabilities to build a tough, integrated position from which extrication would be difficult, to be sure. Russia’s defensive operations do not serve as a simple shield, but rather, as a shield capable of also delivering well-directed, concentrated punches on the opposition army. Russia’s paradoxical use of offensive operations to set up the defense might indicate an ascendency of the defense as the preferred method of war in forthcoming conflicts.

These capabilities will pose enormous challenges to U.S. and allied forces in any potential land combat scenario.

Russia’s focus on limited objectives, often in close proximity to its own border, indicates that U.S. Army combined-arms battalions and cavalry squadrons will likely find themselves on the wrong end of the “quality of firsts” (Figure 4). The U.S. Army’s physical distance from those likely battlefields sets the Army at a great disadvantage because it will have to hastily deploy forces to the region, meaning the Army will arrive late; the arrival will also be known (location, time and force composition). The Army will have great difficulty seizing the initiative due to its arrival and movement being known, which weakens the Army’s ability to fight and win decisively. This dynamic provides time, space and understanding for the enemy to further prepare for combat operations and strengthen its integrated defensive positions. Therefore, U.S. Army combined-arms battalions and cavalry squadrons must be prepared to fight through a rugged enemy defense while maintaining the capability for continued offensive operations.

Fox’s entire analysis is well worth reading and pondering. He also published another excellent analysis of Russian hybrid warfare with a General Staff College colleague, Captain (P) Andrew J. Rossow, in Small Wars Journal.

Tank Loss Rates in Combat: Then and Now

wwii-tank-battlefieldAs the U.S. Army and the national security community seek a sense of what potential conflicts in the near future might be like, they see the distinct potential for large tank battles. Will technological advances change the character of armored warfare? Perhaps, but it seems more likely that the next big tank battles – if they occur – will likely resemble those from the past.

One aspect of future battle of great interest to military planners is probably going to tank loss rates in combat. In a previous post, I looked at the analysis done by Trevor Dupuy on the relationship between tank and personnel losses in the U.S. experience during World War II. Today, I will take a look at his analysis of historical tank loss rates.

In general, Dupuy identified that a proportional relationship exists between personnel casualty rates in combat and losses in tanks, guns, trucks, and other equipment. (His combat attrition verities are discussed here.) Looking at World War II division and corps-level combat engagement data in 1943-1944 between U.S., British and German forces in the west, and German and Soviet forces in the east, Dupuy found similar patterns in tank loss rates.

attrition-fig-58

In combat between two division/corps-sized, armor-heavy forces, Dupuy found that the tank loss rates were likely to be between five to seven times the personnel casualty rate for the winning side, and seven to 10 for the losing side. Additionally, defending units suffered lower loss rates than attackers; if an attacking force suffered a tank losses seven times the personnel rate, the defending forces tank losses would be around five times.

Dupuy also discovered the ratio of tank to personnel losses appeared to be a function of the proportion of tanks to infantry in a combat force. Units with fewer than six tanks per 1,000 troops could be considered armor supporting, while those with a density of more than six tanks per 1,000 troops were armor-heavy. Armor supporting units suffered lower tank casualty rates than armor heavy units.

attrition-fig-59

Dupuy looked at tank loss rates in the 1973 Arab-Israeli War and found that they were consistent with World War II experience.

What does this tell us about possible tank losses in future combat? That is a very good question. One guess that is reasonably certain is that future tank battles will probably not involve forces of World War II division or corps size. The opposing forces will be brigade combat teams, or more likely, battalion-sized elements.

Dupuy did not have as much data on tank combat at this level, and what he did have indicated a great deal more variability in loss rates. Examples of this can be found in the tables below.

attrition-fig-53attrition-fig-54

These data points showed some consistency, with a mean of 6.96 and a standard deviation of 6.10, which is comparable to that for division/corps loss rates. Personnel casualty rates are higher and much more variable than those at the division level, however. Dupuy stated that more research was necessary to establish a higher degree of confidence and relevance of the apparent battalion tank loss ratio. So one potentially fruitful area of research with regard to near future combat could very well be a renewed focus on historical experience.

Back To The Future: The Mobile Protected Firepower (MPF) Program

The MPF's historical antecedent: the German Army's 7.5 cm leichtes Infanteriegeschütz.
The MPF’s historical antecedent: the German Army’s 7.5 cm leichtes Infanteriegeschütz.

Historically, one of the challenges of modern combat has been in providing responsive, on-call, direct fire support for infantry. 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.
