Dupuy’s Verities: Offensive Action

Sheridan’s final charge at Winchester by Thune de Thulstrup (ca. 1886) [Library of Congress]

The first of Trevor Dupuy’s Timeless Verities of Combat is:

Offensive action is essential to positive combat results.

As he explained in Understanding War (1987):

This is like saying, “A team can’t score in football unless it has the ball.” Although subsequent verities stress the strength, value, and importance of defense, this should not obscure the essentiality of offensive action to ultimate combat success. Even in instances where a defensive strategy might conceivably assure a favorable war outcome—as was the case of the British against Napoleon, and as the Confederacy attempted in the American Civil War—selective employment of offensive tactics and operations is required if the strategic defender is to have any chance of final victory. [pp. 1-2]

The offensive has long been a staple element of the principles of war. From the 1954 edition of the U.S. Army Field Manual FM 100-5, Field Service Regulations, Operations:

71. Offensive

Only offensive action achieves decisive results. Offensive action permits the commander to exploit the initiative and impose his will on the enemy. The defensive may be forced on the commander, but it should be deliberately adopted only as a temporary expedient while awaiting an opportunity for offensive action or for the purpose of economizing forces on a front where a decision is not sought. Even on the defensive the commander seeks every opportunity to seize the initiative and achieve decisive results by offensive action. [Original emphasis]

Interestingly enough, the offensive no longer retains its primary place in current Army doctrinal thought. The Army consigned its list of the principles of war to an appendix in the 2008 edition of FM 3-0 Operations and omitted them entirely from the 2017 revision. As the current edition of FM 3-0 Operations lays it out, the offensive is now placed on the same par as the defensive and stability operations:

Unified land operations are simultaneous offensive, defensive, and stability or defense support of civil authorities’ tasks to seize, retain, and exploit the initiative to shape the operational environment, prevent conflict, consolidate gains, and win our Nation’s wars as part of unified action (ADRP 3-0)…

At the heart of the Army’s operational concept is decisive action. Decisive action is the continuous, simultaneous combinations of offensive, defensive, and stability or defense support of civil authorities tasks (ADRP 3-0). During large-scale combat operations, commanders describe the combinations of offensive, defensive, and stability tasks in the concept of operations. As a single, unifying idea, decisive action provides direction for an entire operation. [p. I-16; original emphasis]

It is perhaps too easy to read too much into this change in emphasis. On the very next page, FM 3-0 describes offensive “tasks” thusly:

Offensive tasks are conducted to defeat and destroy enemy forces and seize terrain, resources, and population centers. Offensive tasks impose the commander’s will on the enemy. The offense is the most direct and sure means of seizing and exploiting the initiative to gain physical and cognitive advantages over an enemy. In the offense, the decisive operation is a sudden, shattering action that capitalizes on speed, surprise, and shock effect to achieve the operation’s purpose. If that operation does not destroy or defeat the enemy, operations continue until enemy forces disintegrate or retreat so they no longer pose a threat. Executing offensive tasks compels an enemy to react, creating or revealing additional weaknesses that an attacking force can exploit. [p. I-17]

The change in emphasis likely reflects recent U.S. military experience where decisive action has not yielded much in the way of decisive outcomes, as is mentioned in FM 3-0’s introduction. Joint force offensives in 2001 and 2003 “achieved rapid initial military success but no enduring political outcome, resulting in protracted counterinsurgency campaigns.” The Army now anticipates a future operating environment where joint forces can expect to “work together and with unified action partners to successfully prosecute operations short of conflict, prevail in large-scale combat operations, and consolidate gains to win enduring strategic outcomes” that are not necessarily predicated on offensive action alone. We may have to wait for the next edition of FM 3-0 to see if the Army has drawn valid conclusions from the recent past or not.

Initial SFAB Deployment To Afghanistan Generating High Expectations

Staff Sgt. Braxton Pernice, 6th Battalion, 1st Security Force Assistance Brigade, is pinned his Pathfinder Badge by a fellow 1st SFAB Soldier Nov. 3, 2017, at Fort Benning, Ga., following his graduation from Pathfinder School. Pernice is one of three 1st SFAB Soldiers to graduate the school since the formation of the 1st SFAB. He and Sgt 1st Class Rachel Lyons and Capt. Travis Lowe, all with 6th Bn., 1st SFAB, were among 42 students of Pathfinder School class 001-18 to earn their badge. (U.S. Army photo by Spc. Noelle E. Wiehe)

It appears that the political and institutional stakes associated with the forthcoming deployment of the U.S. Army’s new 1st Security Force Assistance Brigade (SFAB) to Afghanistan have increased dramatically. Amidst the deteriorating security situation, the performance of 1st SFAB is coming to be seen as a test of President Donald Trump’s vow to “win” in Afghanistan and his reported insistence that increased troop and financial commitments demonstrate a “quick return.”

Many will also be watching to see if the SFAB concept validates the Army’s revamped approach to Security Force Assistance (SFA)—an umbrella term for whole-of-government support provided to develop the capability and capacity of foreign security forces and institutions. SFA has long been one of the U.S. government’s primary response to threats of insurgency and terrorism around the world, but its record of success is decidedly mixed.

Earlier this month, the 1st SFAB commander Colonel Scott Jackson reportedly briefed General Joseph Votel, who heads U.S. Central Command, that his unit had less than eight months of training and preparation, instead of an expected 12 months. His personnel had been rushed through the six-week Military Advisor Training Academy curriculum in only two weeks, and that the command suffered from personnel shortages. Votel reportedly passed these concerns to U.S. Army Chief of Staff General Mark Milley.

Competing Mission Priorities

Milley’s brainchild, the SFABs are intended to improve the Army’s ability to conduct SFA and to relieve line Brigade Combat Teams (BCTs) of responsibility for conducting it. Committing BCTs to SFA missions has been seen as both keeping them from more important conventional missions and inhibiting their readiness for high-intensity combat.

However, 1st SFAB may be caught out between two competing priorities: to adequately train Afghan forces and also to partner with and support them in combat operations. The SFABs are purposely optimized for training and advising, but they are not designed for conducting combat operations. They lack a BCT’s command, control and intelligence and combat assets. Some veteran military advisors have pointed out that BCTs are able to control battlespace and possess organic force protection, two capabilities the SFABs lack. While SFAB personnel will advise and accompany Afghan security forces in the field, they will not be able to support them in combat with them the way BCTs can. The Army will also have to deploy additional combat troops to provide sufficient force protection for 1st SFAB’s trainers.

Institutional Questions

The deviating requirements for training and combat advising may be the reason the Army appears to be providing the SFABs with capabilities that resemble those of Army Special Forces (ARSOF) personnel and units. ARSOF’s primary mission is to operate “by, with and through” indigenous forces. While Milley made clear in the past that the SFABs were not ARSOF, they do appear to include some deliberate similarities. While organized overall as a conventional BCT, the SFAB’s basic tactical teams include 12 personnel, like an ARSOF Operational Detachment A (ODA). Also like an ODA, the SFAB teams include intelligence and medical non-commissioned officers, and are also apparently being assigned dedicated personnel for calling in air and fire support (It is unclear from news reports if the SFAB teams include regular personnel trained in basic for call for fire techniques or if they are being given highly-skilled joint terminal attack controllers (JTACs).)

SFAB personnel have been selected using criteria used for ARSOF recruitment and Army Ranger physical fitness standards. They are being given foreign language training at the Military Advisor Training Academy at Fort Benning, Georgia.

The SFAB concept has drawn some skepticism from the ARSOF community, which sees the train, advise, and assist mission as belonging to it. There are concerns that SFABs will compete with ARSOF for qualified personnel and the Army has work to do to create a viable career path for dedicated military advisors. However, as Milley has explained, there are not nearly enough ARSOF personnel to effectively staff the Army’s SFA requirements, let alone meet the current demand for other ARSOF missions.

An Enduring Mission

Single-handedly rescuing a floundering 16-year, $70 billion effort to create an effective Afghan army as well as a national policy that suffers from basic strategic contradictions seems like a tall order for a brand-new, understaffed Army unit. At least one veteran military advisor has asserted that 1st SFAB is being “set up to fail.”

Yet, regardless of how well it performs, the SFA requirement will neither diminish nor go away. The basic logic behind the SFAB concept remains valid. It is possible that a problematic deployment could inhibit future recruiting, but it seems more likely that the SFABs and Army military advising will evolve as experience accumulates. SFA may or may not be a strategic “game changer” in Afghanistan, but as a former Army combat advisor stated, “It sounds low risk and not expensive, even when it is, [but] it’s not going away whether it succeeds or fails.”

The U.S. Army recently announced that the newly-created 1st Security Force Assistance Brigade (SFAB) will deploy to Afghanistan under the command of Colonel Scott Jackson in the spring of 2018 in support of the ongoing effort to train and advise Afghan security forces. 1st SFAB personnel formed the initial classes at the Military Advisor Training Academy (MATA) in August 2017 at Fort Benning, Georgia; approximately 525 had completed the course by November.

The Army intends to establish five Regular Army and one Army National Guard SFABs. In December it stated that the 2nd SFAB would stand up in January 2018 at Fort Bragg, North Carolina.

The Army created the SFABs and MATA in an effort to improve its capabilities to resource and conduct Security Force Assistance (SFA) missions and to relieve line Brigade Combat Teams (BCTs) of these responsibilities. Each SFAB will be manned by 800 senior and noncommissioned volunteer officers with demonstrated experience training and advising foreign security forces.

Specialized training at MATA includes language, foreign weapons, and the Joint Fires Observer course. SFAB commanders and leaders have previous command experience and enlisted advisors hold the rank of sergeant and above. As of August 2017, recruiting for the first unit had been short by approximately 350 personnel, though the shortfall appears to have been remedied. The Army is working to address policies and regulations with regard to promotion rates and boards, selection boards, and special pay.in order to formalize a SFAB career path

Russian General Staff Chief Dishes On Military Operations In Syria

General of the Army Valeriy Gerasimov, Chief of the General Staff of the Armed Forces of the Russian Federation and First Deputy Minister of Defence of the Russian Federation [Wikipedia]

General of the Army Valery Gerasimov, Chief of the General Staff of the Armed Forces of Russia, provided detailed information on Russian military operations in Syria in an interview published in Komsomolskaya Pravda on the day after Christmas.

Maxim A. Suchkov, the Russian coverage editor for Al-Monitor, provided an English-language summary on Twitter.

While Gerasimov’s comments should be read critically, they do provide a fascinating insight into the Russian perspective on the intervention in Syria, which has proved remarkably successful with an economical investment in resources and money.

Gerasimov stated that planning for Russian military operations used Operation Anadyr, the secret deployment of troops and weapons to Cuba in 1962, as a template. A large-scale deployment of ground forces was ruled out at the start. The Syrian government army and militias were deemed combat-capable despite heavy combat losses, so the primary supporting tasks were identified as targeting and supporting fires to disrupt enemy “control systems.”

The clandestine transfer of up to 50 Russian combat aircraft to Hmeimim Air Base in Latakia, Syria, began a month before the beginning of operations in late-September 2015. Logistical and infrastructure preparations took much longer. The most difficult initial challenge, according to Gerasimov, was coordinating Russian air support with Syrian government ground forces, but it was resolved over time.

The Russians viewed Daesh (ISIS) forces battling the Syrian government as a regular army employing combat tactics, fielding about 1,500 tanks and 1,200 artillery pieces seized from Syria and Iraq.

While the U.S.-led coalition conducted 8-10 air strikes per day against Daesh in Syria, the Russians averaged 60-70, with a peak of 120-140. Gerasimov attributed the disparity to the fact that the coalition was seeking to topple Bashar al-Assad’s regime, not the defeat of Daesh. He said that while the Russians obtained cooperation with the U.S. over aerial deconfliction and “de-escalation” in southern Syria, offers for joint planning, surveillance, and strikes were turned down. Gerasimov asserted that Daesh would have been defeated faster had there been more collaboration.

More controversially, Gerasimov claimed that U.S.-supported New Syrian Army rebel forces at Al Tanf and Al-Shaddidi were “virtually” Daesh militants, seeking to destabilize Syria, and complained that the U.S. refused Russian access to the camp at Rukban.

According to Russian estimates, there were a total of 59,000 Daesh fighters in September 2015 and that 10,000 more were recruited. Now there are only 2,800 and most militants are returning to their home countries. Most are believed heading to Libya, some to Afghanistan, and others to Southwest Asia.

Gerasimov stated that Russia will continue to deploy sufficient forces in Syria to provide offensive support if needed and the Mediterranean naval presence will be maintained. The military situation remains unstable and the primary objective is the elimination of remaining al Nusra/Hay’at Tahrir al-Sham (al Qaida in Syria) fighters.

48,000 Russian troops were rotated through Syria, most for three months, from nearly 90% of Russian Army divisions and half of the regiments and brigades. 200 new weapons were tested and “great leaps” were made in developing and using drone technology, which Gerasimov deemed now “integral” to the Russian military.

Gerasimov said that he briefed Russian Defense Minister Sergei Shoigu on Syria twice daily, and Shoigu updated Russian President Vladimir Putin “once or twice a week.” All three would “sometimes” meet to plan together and Gerasimov averred that “Putin sets [the] goals, tasks, [and] knows all the details on every level.

How Does the U.S. Army Calculate Combat Power? ¯\_(ツ)_/¯

The constituents of combat power as described in current U.S. military doctrine. [The Lightning Press]

One of the fundamental concepts of U.S. warfighting doctrine is combat power. The current U.S. Army definition is “the total means of destructive, constructive, and information capabilities that a military unit or formation can apply at a given time. (ADRP 3-0).” It is the construct commanders and staffs are taught to use to assess the relative effectiveness of combat forces and is woven deeply throughout all aspects of U.S. operational thinking.

To execute operations, commanders conceptualize capabilities in terms of combat power. Combat power has eight elements: leadership, information, mission command, movement and maneuver, intelligence, fires, sustainment, and protection. The Army collectively describes the last six elements as the warfighting functions. Commanders apply combat power through the warfighting functions using leadership and information. [ADP 3-0, Operations]

Yet, there is no formal method in U.S. doctrine for estimating combat power. The existing process is intentionally subjective and largely left up to judgment. This is problematic, given that assessing the relative combat power of friendly and opposing forces on the battlefield is the first step in Course of Action (COA) development, which is at the heart of the U.S. Military Decision-Making Process (MDMP). Estimates of combat power also figure heavily in determining the outcomes of wargames evaluating proposed COAs.

The Existing Process

The Army’s current approach to combat power estimation is outlined in Field Manual (FM) 6-0 Commander and Staff Organization and Operations (2014). Planners are instructed to “make a rough estimate of force ratios of maneuver units two levels below their echelon.” They are then directed to “compare friendly strengths against enemy weaknesses, and vice versa, for each element of combat power.” It is “by analyzing force ratios and determining and comparing each force’s strengths and weaknesses as a function of combat power” that planners gain insight into tactical and operational capabilities, perspectives, vulnerabilities, and required resources.

That is it. Planners are told that “although the process uses some numerical relationships, the estimate is largely subjective. Assessing combat power requires assessing both tangible and intangible factors, such as morale and levels of training.” There is no guidance as to how to determine force ratios [numbers of troops or weapons systems?]. Nor is there any description of how to relate force calculations to combat power. Should force strengths be used somehow to determine a combat power value? Who knows? No additional doctrinal or planning references are provided.

Planners then use these subjective combat power assessments as they shape potential COAs and test them through wargaming. Although explicitly warned not to “develop and recommend COAs based solely on mathematical analysis of force ratios,” they are invited at this stage to consult a table of “minimum historical planning ratios as a starting point.” The table is clearly derived from the ubiquitous 3-1 rule of combat. Contrary to what FM 6-0 claims, neither the 3-1 rule nor the table have a clear historical provenance or any sort of empirical substantiation. There is no proven validity to any of the values cited. It is not even clear whether the “historical planning ratios” apply to manpower, firepower, or combat power.

During this phase, planners are advised to account for “factors that are difficult to gauge, such as impact of past engagements, quality of leaders, morale, maintenance of equipment, and time in position. Levels of electronic warfare support, fire support, close air support, civilian support, and many other factors also affect arraying forces.” FM 6-0 offers no detail as to how these factors should be measured or applied, however.

FM 6-0 also addresses combat power assessment for stability and civil support operations through troop-to-task analysis. Force requirements are to be based on an estimate of troop density, a “ratio of security forces (including host-nation military and police forces as well as foreign counterinsurgents) to inhabitants.” The manual advises that most “most density recommendations fall within a range of 20 to 25 counterinsurgents for every 1,000 residents in an area of operations. A ratio of twenty counterinsurgents per 1,000 residents is often considered the minimum troop density required for effective counterinsurgency operations.”

While FM 6-0 acknowledges that “as with any fixed ratio, such calculations strongly depend on the situation,” it does not mention that any references to force level requirements, tie-down ratios, or troop density were stripped from both Joint and Army counterinsurgency manuals in 2013 and 2014. Yet, this construct lingers on in official staff planning doctrine. (Recent research challenged the validity of the troop density construct but the Defense Department has yet to fund any follow-on work on the subject.)

The Army Has Known About The Problem For A Long Time

The Army has tried several solutions to the problem of combat power estimation over the years. In the early 1970s, the U.S. Army Center for Army Analysis (CAA; known then as the U.S. Army Concepts & Analysis Agency) developed the Weighted Equipment Indices/Weighted Unit Value (WEI/WUV or “wee‑wuv”) methodology for calculating the relative firepower of different combat units. While WEI/WUV’s were soon adopted throughout the Defense Department, the subjective nature of the method gradually led it to be abandoned for official use.

In the 1980s and 1990s, the U.S. Army Command & General Staff College (CGSC) published the ST 100-9 and ST 100-3 student workbooks that contained tables of planning factors that became the informal basis for calculating combat power in staff practice. The STs were revised regularly and then adapted into spreadsheet format in the late 1990s. The 1999 iteration employed WEI/WEVs as the basis for calculating firepower scores used to estimate force ratios. CGSC stopped updating the STs in the early 2000s, as the Army focused on irregular warfare.

With the recently renewed focus on conventional conflict, Army staff planners are starting to realize that their planning factors are out of date. In an attempt to fill this gap, CGSC developed a new spreadsheet tool in 2012 called the Correlation of Forces (COF) calculator. It apparently drew upon analysis done by the U.S. Army Training and Doctrine Command Analysis Center (TRAC) in 2004 to establish new combat unit firepower scores. (TRAC’s methodology is not clear, but if it is based on this 2007 ISMOR presentation, the scores are derived from runs by an unspecified combat model modified by factors derived from the Army’s unit readiness methodology. If described accurately, this would not be an improvement over WEI/WUVs.)

The COF calculator continues to use the 3-1 force ratio tables. It also incorporates a table for estimating combat losses based on force ratios (this despite ample empirical historical analysis showing that there is no correlation between force ratios and casualty rates).

While the COF calculator is not yet an official doctrinal product, CGSC plans to add Marine Corps forces to it for use as a joint planning tool and to incorporate it into the Army’s Command Post of the Future (CPOF). TRAC is developing a stand-alone version for use by force developers.

The incorporation of unsubstantiated and unvalidated concepts into Army doctrine has been a long standing problem. In 1976, Huba Wass de Czege, then an Army major, took both “loosely structured and unscientific analysis” based on intuition and experience and simple counts of gross numbers to task as insufficient “for a clear and rigorous understanding of combat power in a modern context.” He proposed replacing it with a analytical framework for analyzing combat power that accounted for both measurable and intangible factors. Adopting a scrupulous method and language would overcome the simplistic tactical analysis then being taught. While some of the essence of Wass de Czege’s approach has found its way into doctrinal thinking, his criticism of the lack of objective and thorough analysis continues to echo (here, here, and here, for example).

Despite dissatisfaction with the existing methods, little has changed. The problem with this should be self-evident, but I will give the U.S. Naval War College the final word here:

Fundamentally, all of our approaches to force-on-force analysis are underpinned by theories of combat that include both how combat works and what matters most in determining the outcomes of engagements, battles, campaigns, and wars. The various analytical methods we use can shed light on the performance of the force alternatives only to the extent our theories of combat are valid. If our theories are flawed, our analytical results are likely to be equally wrong.

I never knew him, but his work was a major influence on my work. In the late 1960s, Gurr and Professors Ivo and Rosalind Feierabend led two independent quantitative analysis efforts on the causes of revolutions. Even though they each created their own databases and independently did their own regression analysis of the subject, they came up with similar results. I did have several discussions with Dr. Ivo Feierabend while I was doing some independent work on the causes of revolution.

Today’s edition of TDI Friday Read is a compilation of posts addressing the question of manpower and counterinsurgency. The first four posts summarize research on the question undertaken during the first decade of the 21st century, while the Afghan and Iraqi insurgencies were in full bloom. Despite different research questions and analytical methodologies, each of the studies concluded that there is a relationship between counterinsurgent manpower and counterinsurgency outcomes.

The fifth post addresses the U.S. Army’s lack of a formal methodology for calculating manpower requirements for counterinsurgencies and contingency operations.

The Historical Combat Effectiveness of Lighter-Weight Armored Forces

In 2001, The Dupuy Institute conducted a study for the U.S. Army Center for Army Analysis (CAA) on the historical effectiveness of lighter-weight armored forces. At the time, the Army had developed a requirement for an Interim Armored Vehicle (IAV), lighter and more deployable than existing M1 Abrams Main Battle Tank and the M2 Bradley Infantry Fighting Vehicle, to form the backbone of the future “Objective Force.” This program would result in development of the Stryker Infantry Fighting Vehicle.

CAA initiated the TDI study at the request of Walter W. “Don” Hollis, then the Deputy Undersecretary of the Army for Operations Research (a position that was eliminated in 2006.) TDI completed and submitted “The Historical Combat Effectiveness of Lighter-Weight Armored Forces” to CAA in August 2001. It examined the effectiveness of light and medium-weight armored forces in six scenarios:

  • Conventional conflicts against an armor supported or armor heavy force.
  • Emergency insertions against an armor supported or armor heavy force.
  • Conventional conflict against a primarily infantry force (as one might encounter in sub-Saharan Africa).
  • Emergency insertion against a primarily infantry force.
  • A small to medium insurgency (includes an insurgency that develops during a peacekeeping operation).
  • A peacekeeping operation or similar Operation Other Than War (OOTW) that has some potential for violence.

The historical data the study drew upon came from 146 cases of small-scale contingency operations; U.S. involvement in Vietnam; German counterinsurgency operations in the Balkans, 1941-1945; the Philippines Campaign, 1941-42; the Normandy Campaign, 1944; the Korean War 1950-51; the Persian Gulf War, 1990-91; and U.S. and European experiences with light and medium-weight armor in World War II.

The major conclusions of the study were:

Small Scale Contingency Operations (SSCOs)

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It would appear that existing systems (M-2 and M-3 Bradley and M-113) can fulfill most requirements. Current plans to develop an advanced LAV-type vehicle may cover almost all other shortfalls. Mine protection is a design feature that should be emphasized.
  2. Implications for the Interim Brigade Combat Team (IBCT). The need for armor in SSCOs that are not conventional or closely conventional in nature is limited and rarely approaches the requirements of a brigade-size armored force.

Insurgencies

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It would appear that existing systems (M-2 and M-3 Bradley and M-113) can fulfill most requirements. The armor threat in insurgencies is very limited until the later stages if the conflict transitions to conventional war. In either case, mine protection is a design feature that may be critical.
  2. Implications for the Interim Brigade Combat Team (IBCT). It is the nature of insurgencies that rapid deployment of armor is not essential. The armor threat in insurgencies is very limited until the later stages if the conflict transitions to a conventional war and rarely approaches the requirements of a brigade-size armored force.

Conventional Warfare

Conventional Conflict Against An Armor Supported Or Armor Heavy Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It may be expected that opposing heavy armor in a conventional armor versus armor engagement could significantly overmatch the IAV. In this case the primary requirement would be for a weapon system that would allow the IAV to defeat the enemy armor before it could engage the IAV.
  2. Implications for the Interim Brigade Combat Team (IBCT). The IBCT could substitute as an armored cavalry force in such a scenario.

Conventional Conflict Against A Primarily Infantry Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. This appears to be little different from those conclusions found for the use of armor in SSCOs and Insurgencies.
  2. Implications for the Interim Brigade Combat Team (IBCT). The lack of a major armor threat will make the presence of armor useful.

Emergency Insertion Against An Armor Supported Or Armor Heavy Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It appears that the IAV may be of great use in an emergency insertion. However, the caveat regarding the threat of being overmatched by conventional heavy armor mentioned above should not be ignored. In this case the primary requirement would be for a weapon system that would allow the IAV to defeat the enemy armor before it could engage the IAV.
  2. Implications for the Interim Brigade Combat Team (IBCT). Although the theoretical utility of the IBCT in this scenario may be great it should be noted that The Dupuy Institute was only able to find one comparable case of such a deployment which resulted in actual conflict in US military history in the last 60 years (Korea, 1950). In this case the effect of pushing forward light tanks into the face of heavier enemy tanks was marginal.

Emergency Insertion Against A Primarily Infantry Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. The lack of a major armor threat in this scenario will make the presence of any armor useful. However, The Dupuy Institute was unable to identify the existence of any such cases in the historical record.
  2. Implications for the Interim Brigade Combat Team (IBCT). The lack of a major armor threat will make the presence of any armor useful. However, The Dupuy Institute was unable to identify the existence of any such cases in the historical record.

Other Conclusions

Wheeled Vehicles

  1. There is little historical evidence one way or the other establishing whether wheels or tracks are the preferable feature of AFVs.

Vehicle Design

  1. In SSCOs access to a large-caliber main gun was useful for demolishing obstacles and buildings. This capability is not unique and could be replaced by AT missiles armed CFVs, IFVs and APCs.
  2. Any new lighter tank-like vehicle should make its gun system the highest priority, armor secondary and mobility and maneuverability tertiary.
  3. Mine protection should be emphasized. Mines were a major threat to all types of armor in many scenarios. In many SSCOs it was the major cause of armored vehicle losses.
  4. The robust carrying capacity offered by an APC over a tank is an advantage during many SSCOs.

Terrain Issues

  1. The use of armor in urban fighting, even in SSCOs, is still limited. The threat to armor from other armor in urban terrain during SSCOs is almost nonexistent. Most urban warfare armor needs, where armor basically serves as a support weapon, can be met with light armor (CFVs, IFVs, and APCs).
  2. Vehicle weight is sometimes a limiting factor in less developed areas. In all cases where this was a problem, there was not a corresponding armor threat. As such, in almost all cases, the missions and tasks of a tank can be fulfilled with other light armor (CFVs, IFVs, or APCs).
  3. The primary terrain problem is rivers and flooded areas. It would appear that in difficult terrain, especially heavily forested terrain (areas with lots of rainfall, like jungles), a robust river crossing capability is required.

Operational Factors

  1. Emergency insertions and delaying actions sometimes appear to be a good way to lose lots of armor for limited gain. This tends to come about due to terrain problems, enemy infiltration and bypassing, and the general confusion prevalent in such operations. The Army should be careful not to piecemeal assets when inserting valuable armor resources into a ‘hot’ situation. In many cases holding back and massing the armor for defense or counter-attack may be the better option.
  2. Transportability limitations have not been a major factor in the past for determining whether lighter or heavier armor were sent into a SSCO or a combat environment.

Casualty Sensitivity

  1. In a SSCO or insurgency, in most cases the weight and armor of the AFVs is not critical. As such, one would not expect any significant changes in losses regardless of the type of AFV used (MBT, medium-weight armor, or light armor). However, the perception that US forces are not equipped with the best-protected vehicle may cause some domestic political problems. The US government is very casualty sensitive during SSCOs. Furthermore, the current US main battle tank particularly impressive, and may help provide some additional intimidation in SSCOs.
  2. In any emergency insertion scenario or conventional war scenario, the use of lighter armor could result in higher US casualties and lesser combat effectiveness. This will certainly cause some domestic political problems and may impact army morale. However by the same token, light infantry forces, unsupported by easily deployable armor could present a worse situation.

New U.S. Army Security Force Assistance Brigades Face Challenges

The recent deaths of four U.S. Army Special Forces (ARSOF) operators in an apparent ambush in support of the Train and Assist mission in Niger appears to have reminded Congress of the enormous scope of ongoing Security Force Assistance (SFA) activities being conducted world-wide by the Defense Department. U.S. military forces deployed to 138 countries in 2016, the majority of which were by U.S. Special Operations Forces (SOF) conducting SFA activities. (While SFA deployments continue at a high tempo, the number of U.S. active-duty troops stationed overseas has fallen below 200,000 for the first time in 60 years, interestingly enough.)

SFA is the umbrella term for U.S. whole-of-government support provided to develop the capability and capacity of foreign security forces and institutions. SFA is intended to help defend host nations from external and internal threats, and encompasses foreign internal defense (FID), counterterrorism (CT), counterinsurgency (COIN), and stability operations.

Last year, the U.S. Army announced that it would revamp its contribution to SFA by creating a new type of unit, the Security Force Assistance Brigade (SFAB), and by establishing a Military Advisor Training Academy. The first of six projected SFABs is scheduled to stand up this month at Ft. Benning, Georgia.

Rick Montcalm has a nice piece up at the Modern War Institute describing the doctrinal and organizational challenges the Army faces in implementing the SFABs. The Army’s existing SFA structure features regionally-aligned Brigade Combat Teams (BCTs) providing combined training and partnered mission assistance for foreign conventional forces from the team to company level, while ARSOF focuses on partner-nation counterterrorism missions and advising and assisting commando and special operations-type forces.

Ideally, the SFABs would supplement and gradually replace most, but not all, of the regionally-aligned BCTs to allow them to focus on warfighting tasks. Concerns have arisen with the ARSOF community, however, that a dedicated SFAB force would encroach functionally on its mission and compete within the Army for trained personnel. The SFABs currently lack the intelligence capabilities necessary to successfully conduct the advisory mission in hostile environments. Although U.S. Army Chief of Staff General Mark Milley asserts that the SFABs are not Special Forces, properly preparing them for advise and assist roles would make them very similar to existing ARSOF.

Montcalm also points out that Army personnel policies complicate maintain the SFABs in the long-term. The Army has not created a specific military advisor career field and volunteering to serve in a SFAB could complicate the career progression of active duty personnel. Although the Army has taken steps to address this, the prospect of long repeat overseas tours and uncertain career prospects has forced the service to offer cash incentives and automatic promotions to bolster SFAB recruiting. As of August, the 1st SFAB needed 350 more soldiers to fully man the unit, which was scheduled to be operational in November.

SFA and the Army’s role in it will not decline anytime soon, so there is considerable pressure to make the SFAB concept successful. Yet, in light of the largely unsuccessful efforts to build effective security forces in Iraq and Afghanistan, it remains an open question if the SFAB’s themselves will be enough to remedy the Army’s problematic approach to building partner capacity.
