Active Defense, Forward Defense, and A2/AD in Eastern Europe

The current military and anti-access/area denial situation in Eastern Europe. [Map and overlay derived from situation map by Thomas C. Thielen (@noclador) https://twitter.com/noclador/status/1079999716333703168; and Ian Williams, “The Russia – NATO A2AD Environment,” Missile Threat, Center for Strategic and International Studies, published January 3, 2017, last modified November 29, 2018, https://missilethreat.csis.org/russia-nato-a2ad-environment/]

In an article published by West Point’s Modern War Institute last month, “The US Army is Wrong on Future War,” Nathan Jennings, Amos Fox and Adam Taliaferro laid out a detailed argument that current and near-future political, strategic, and operational realities augur against the Army’s current doctrinal conceptualization for Multi-Domain Operations (MDO).

[T]he US Army is mistakenly structuring for offensive clashes of mass and scale reminiscent of 1944 while competitors like Russia and China have adapted to twenty-first-century reality. This new paradigm—which favors fait accompli acquisitions, projection from sovereign sanctuary, and indirect proxy wars—combines incremental military actions with weaponized political, informational, and economic agendas under the protection of nuclear-fires complexes to advance territorial influence…

These factors suggest, cumulatively, that the advantage in military confrontation between great powers has decisively shifted to those that combine strategic offense with tactical defense.

As a consequence, the authors suggested that “the US Army should recognize the evolved character of modern warfare and embrace strategies that establish forward positions of advantage in contested areas like Eastern Europe and the South China Sea. This means reorganizing its current maneuver-centric structure into a fires-dominant force with robust capacity to defend in depth.”

Forward Defense, Active Defense, and AirLand Battle

To illustrate their thinking, Jennings, Fox, and Taliaferro invoked a specific historical example:

This strategic realignment should begin with adopting an approach more reminiscent of the US Army’s Active Defense doctrine of the 1970s than the vaunted AirLand Battle concept of the 1980s. While many distain (sic) Active Defense for running counter to institutional culture, it clearly recognized the primacy of the combined-arms defense in depth with supporting joint fires in the nuclear era. The concept’s elevation of the sciences of terrain and weaponry at scale—rather than today’s cult of the offense—is better suited to the current strategic environment. More importantly, this methodology would enable stated political aims to prevent adversary aggression rather than to invade their home territory.

In the article’s comments, many pushed back against reviving Active Defense thinking, which has apparently become indelibly tarred with the derisive criticism that led to its replacement by AirLand Battle in the 1980s. As the authors gently noted, much of this resistance stemmed from the perceptions of Army critics that Active Defense was passive and defensively-oriented, overly focused on firepower, and suspicions that it derived from operations research analysts reducing warfare and combat to a mathematical “battle calculus.”

While AirLand Battle has been justly lauded for enabling U.S. military success against Iraq in 1990-91 and 2003 (a third-rank, non-nuclear power it should be noted), it always elided the fundamental question of whether conventional deep strikes and operational maneuver into the territory of the Soviet Union’s Eastern European Warsaw Pact allies—and potentially the Soviet Union itself—would have triggered a nuclear response. The criticism of Active Defense similarly overlooked the basic political problem that led to the doctrine in the first place, namely, the need to provide a credible conventional forward defense of West Germany. Keeping the Germans actively integrated into NATO depended upon assurances that a Soviet invasion could be resisted effectively without resorting to nuclear weapons. Indeed, the political cohesion of the NATO alliance itself rested on the contradiction between the credibility of U.S. assurances that it would defend Western Europe with nuclear weapons if necessary and the fears of alliance members that losing a battle for West Germany would make that necessity a reality.

Forward Defense in Eastern Europe

A cursory look at the current military situation in Eastern Europe along with Russia’s increasingly robust anti-access/area denial (A2/AD) capabilities (see map) should clearly illustrate the logic behind a doctrine of forward defense. U.S. and NATO troops based in Western Europe would have to run a gauntlet of well protected long-range fires systems just to get into battle in Ukraine or the Baltics. Attempting operational maneuver at the end of lengthy and exposed logistical supply lines would seem to be dauntingly challenging. The U.S. 2nd U.S. Cavalry ABCT Stryker Brigade Combat Team based in southwest Germany appears very much “lone and lonely.” It should also illustrate the difficulties in attacking the Russian A2/AD complex; an act, which Jennings, Fox, and Taliaferro remind, that would actively court a nuclear response.

In this light, Active Defense—or better—a MDO doctrine of forward defense oriented on “a fires-dominant force with robust capacity to defend in depth,” intended to “enable stated political aims to prevent adversary aggression rather than to invade their home territory,” does not really seem foolishly retrograde after all.

U.S. Army Doctrine and Future Warfare

Pre-war U.S. Army warfighting doctrine led to fielding the M10, M18 and M36 tank destroyers to counter enemy tanks. Their relatively ineffective performance against German panzers in Europe during World War II has been seen as the result of flawed thinking about tank warfare. [Wikimedia]

Two recently published articles on current U.S. Army doctrine development and the future of warfare deserve to be widely read:

“An Army Caught in the Middle Between Luddites, Luminaries, and the Occasional Looney,”

The first, by RAND’s David Johnson, is titled “An Army Caught in the Middle Between Luddites, Luminaries, and the Occasional Looney,” published by War on the Rocks.

Johnson begins with an interesting argument:

Contrary to what it says, the Army has always been a concepts-based, rather than a doctrine-based, institution. Concepts about future war generate the requirements for capabilities to realize them… Unfortunately, the Army’s doctrinal solutions evolve in war only after the failure of its concepts in its first battles, which the Army has historically lost since the Revolutionary War.

The reason the Army fails in its first battles is because its concepts are initially — until tested in combat — a statement of how the Army “wants to fight” and rarely an analytical assessment of how it “will have to fight.”

Starting with the Army’s failure to develop its own version of “blitzkrieg” after World War I, Johnson identified conservative organizational politics, misreading technological advances, and a stubborn refusal to account for the capabilities of potential adversaries as common causes for the inferior battlefield weapons and warfighting methods that contributed to its impressive string of lost “first battles.”

Conversely, Johnson credited the Army’s novel 1980s AirLand Battle doctrine as the product of an honest assessment of potential enemy capabilities and the development of effective weapon systems that were “based on known, proven technologies that minimized the risk of major program failures.”

“The principal lesson in all of this” he concluded, “is that the U.S. military should have a clear problem that it is trying to solve to enable it to innovate, and is should realize that innovation is generally not invention.” There are “also important lessons from the U.S. Army’s renaissance in the 1970s, which also resulted in close cooperation between the Army and the Air Force to solve the shared problem of the defense of Western Europe against Soviet aggression that neither could solve independently.”

“The US Army is Wrong on Future War”

The other article, provocatively titled “The US Army is Wrong on Future War,” was published by West Point’s Modern War Institute. It was co-authored by Nathan Jennings, Amos Fox, and Adam Taliaferro, all graduates of the School of Advanced Military Studies, veterans of Iraq and Afghanistan, and currently serving U.S. Army officers.

They argue that

the US Army is mistakenly structuring for offensive clashes of mass and scale reminiscent of 1944 while competitors like Russia and China have adapted to twenty-first-century reality. This new paradigm—which favors fait accompli acquisitions, projection from sovereign sanctuary, and indirect proxy wars—combines incremental military actions with weaponized political, informational, and economic agendas under the protection of nuclear-fires complexes to advance territorial influence. The Army’s failure to conceptualize these features of the future battlefield is a dangerous mistake…

Instead, they assert that the current strategic and operational realities dictate a far different approach:

Failure to recognize the ascendancy of nuclear-based defense—with the consequent potential for only limited maneuver, as in the seventeenth century—incurs risk for expeditionary forces. Even as it idealizes Patton’s Third Army with ambiguous “multi-domain” cyber and space enhancements, the US Army’s fixation with massive counter-offensives to defeat unrealistic Russian and Chinese conquests of Europe and Asia misaligns priorities. Instead of preparing for past wars, the Army should embrace forward positional and proxy engagement within integrated political, economic, and informational strategies to seize and exploit initiative.

The factors they cite that necessitate the adoption of positional warfare include nuclear primacy; sanctuary of sovereignty; integrated fires complexes; limited fait accompli; indirect proxy wars; and political/economic warfare.

“Given these realities,” Jennings, Fox, and Taliaferro assert, “the US Army must adapt and evolve to dominate great-power confrontation in the nuclear age. As such, they recommend that the U.S. (1) adopt “an approach more reminiscent of the US Army’s Active Defense doctrine of the 1970s than the vaunted AirLand Battle concept of the 1980s,” (2) “dramatically recalibrate its approach to proxy warfare; and (3) compel “joint, interagency and multinational coordination in order to deliberately align economic, informational, and political agendas in support of military objectives.”

Future U.S. Army Doctrine: How It Wants to Fight or How It Has to Fight?

Readers will find much with which to agree or disagree in each article, but they both provide viewpoints that should supply plenty of food for thought. Taken together they take on a different context. The analysis put forth by Jenninigs, Fox, and Taliaferro can be read as fulfilling Johnson’s injunction to base doctrine on a sober assessment of the strategic and operational challenges presented by existing enemy capabilities, instead of as an aspirational concept for how the Army would prefer to fight a future war. Whether or not Jennings, et al, have accurately forecasted the future can be debated, but their critique should raise questions as to whether the Army is repeating past doctrinal development errors identified by Johnson.

U.S. Army Multi-Domain Operations Concept Continues Evolving

[Sgt. Meghan Berry, US Army/adapted by U.S. Army Modern War Institute]

The U.S. Army Training and Doctrine Command (TRADOC) released draft version 1.5 of its evolving Multi-Domain Operations (MDO) future operating concept last week. Entitled TRADOC Pamphlet 525-3-1, “The U.S. Army in Multi-Domain Operations 2028,” this iteration updates the initial Multi-Domain Battle (MDB) concept issued in October 2017.

According to U.S. Army Chief of Staff (and Chairman of the Joint Chiefs of Staff nominee) General Mark Milley, MDO Concept 1.5 is the first step in the doctrinal evolution. “It describes how U.S. Army forces, as part of the Joint Force, will militarily compete, penetrate, dis-integrate, and exploit our adversaries in the future.”

TRADOC Commander General Stuart Townsend summarized the draft concept thusly:

The U.S. Army in Multi-Domain Operations 2028 concept proposes a series of solutions to solve the problem of layered standoff. The central idea in solving this problem is the rapid and continuous integration of all domains of warfare to deter and prevail as we compete short of armed conflict. If deterrence fails, Army formations, operating as part of the Joint Force, penetrate and dis-integrate enemy anti-access and area denial systems;exploit the resulting freedom of maneuver to defeat enemy systems, formations and objectives and to achieve our own strategic objectives; and consolidate gains to force a return to competition on terms more favorable to the U.S., our allies and partners.

To achieve this, the Army must evolve our force, and our operations, around three core tenets. Calibrated force posture combines position and the ability to maneuver across strategic distances. Multi-domain formations possess the capacity, endurance and capability to access and employ capabilities across all domains to pose multiple and compounding dilemmas on the adversary. Convergence achieves the rapid and continuous integration of all domains across time, space and capabilities to overmatch the enemy. Underpinning these tenets are mission command and disciplined initiative at all warfighting echelons. (original emphasis)

For a look at the evolution of the Army and U.S. Marine Corps doctrinal thinking about multi-domain warfare since early 2017:

U.S. Army Updates Draft Multi-Domain Battle Operating Concept

 

Interchangeability Of Fire And Multi-Domain Operations

Soviet “forces and resources” chart. [Richard Simpkin, Deep Battle: The Brainchild of Marshal Tukhachevskii (Brassey’s: London, 1987) p. 254]

With the emergence of the importance of cross-domain fires in the U.S. effort to craft a joint doctrine for multi-domain operations, there is an old military concept to which developers should give greater consideration: interchangeability of fire.

This is an idea that British theorist Richard Simpkin traced back to 19th century Russian military thinking, which referred to it then as the interchangeability of shell and bayonet. Put simply, it was the view that artillery fire and infantry shock had equivalent and complimentary effects against enemy troops and could be substituted for one another as circumstances dictated on the battlefield.

The concept evolved during the development of the Russian/Soviet operational concept of “deep battle” after World War I to encompass the interchangeability of fire and maneuver. In Soviet military thought, the battlefield effects of fires and the operational maneuver of ground forces were equivalent and complementary.

This principle continues to shape contemporary Russian military doctrine and practice, which is, in turn, influencing U.S. thinking about multi-domain operations. In fact, the idea is not new to Western military thinking at all. Maneuver warfare advocates adopted the concept in the 1980s, but it never found its way into official U.S. military doctrine.

An Idea Who’s Time Has Come. Again.

So why should the U.S. military doctrine developers take another look at interchangeability now? First, the increasing variety and ubiquity of long-range precision fire capabilities is forcing them to address the changing relationship between mass and fires on multi-domain battlefields. After spending a generation waging counterinsurgency and essentially outsourcing responsibility for operational fires to the U.S. Air Force and U.S. Navy, both the U.S. Army and U.S. Marine Corps are scrambling to come to grips with the way technology is changing the character of land operations. All of the services are at the very beginning of assessing the impact of drone swarms—which are themselves interchangeable blends of mass and fires—on combat.

Second, the rapid acceptance and adoption of the idea of cross-domain fires has carried along with it an implicit acceptance of the interchangeability of the effects of kinetic and non-kinetic (i.e. information, electronic, and cyber) fires. This alone is already forcing U.S. joint military thinking to integrate effects into planning and decision-making.

The key component of interchangability is effects. Inherent in it is acceptance of the idea that combat forces have effects on the battlefield that go beyond mere physical lethality, i.e. the impact of fire or shock on a target. U.S. Army doctrine recognizes three effects of fires: destruction, neutralization, and suppression. Russian and maneuver warfare theorists hold that these same effects can be achieved through the effects of operational maneuver. The notion of interchangeability offers a very useful way of thinking about how to effectively integrate the lethality of mass and fires on future battlefields.

But Wait, Isn’t Effects Is A Four-Letter Word?

There is a big impediment to incorporating interchangeability into U.S. military thinking, however, and that is the decidedly ambivalent attitude of the U.S. land warfare services toward thinking about non-tangible effects in warfare.

As I have pointed out before, the U.S. Army (at least) has no effective way of assessing the effects of fires on combat, cross-domain or otherwise, because it has no real doctrinal methodology for calculating combat power on the battlefield. Army doctrine conceives of combat power almost exclusively in terms of capabilities and functions, not effects. In Army thinking, a combat multiplier is increased lethality in the form of additional weapons systems or combat units, not the intangible effects of operational or moral (human) factors on combat. For example, suppression may be a long-standing element in doctrine, but the Army still does not really have a clear idea of what causes it or what battlefield effects it really has.

In the wake of the 1990-91 Gulf War and the ensuing “Revolution in Military Affairs,” the U.S. Air Force led the way forward in thinking about the effects of lethality on the battlefield and how it should be leveraged to achieve strategic ends. It was the motivating service behind the development of a doctrine of “effects based operations” or EBO in the early 2000s.

However, in 2008, U.S. Joint Forces Command commander, U.S Marine General (and current Secretary of Defense) James Mattis ordered his command to no longer “use, sponsor, or export” EBO or related concepts and terms, the underlying principles of which he deemed to be “fundamentally flawed.” This effectively eliminated EBO from joint planning and doctrine. While Joint Forces Command was disbanded in 2011 and EBO thinking remains part of Air Force doctrine, Mattis’s decree pretty clearly showed what the U.S. land warfare services think about battlefield effects.

Table IX shows the distribution of cause of loss by type or armor vehicle. From the distribution it might be inferred that better protected armored vehicles may be less vulnerable to artillery attack. Nevertheless, the heavily armored vehicles still suffered a minimum loss of 5.6 percent due to artillery. Unfortunately the sample size for heavy tanks was very small, 18 of 980 cases or only 1.8 percent of the total.

The data are limited at this time to the seven cases.[6] Further research is necessary to expand the data sample so as to permit proper statistical analysis of the effectiveness of artillery versus tanks.

Curiously, at Kursk, in the case where the highest percent loss was recorded, the German forces opposing the Soviet 1st Tank Army—mainly the XLVIII Panzer Corps of the Fourth Panzer Army—were supported by proportionately fewer artillery pieces (approximately 56 guns and rocket launchers per division) than the US 1st Infantry Division at Dom Bütgenbach (the equivalent of approximately 106 guns per division)[4]. Nor does it appear that the German rate of fire at Kursk was significantly higher than that of the American artillery at Dom Bütgenbach. On 20 July at Kursk, the 150mm howitzers of the 11th Panzer Division achieved a peak rate of fire of 87.21 rounds per gum. On 21 December at Dom Bütgenbach, the 155mm howitzers of the 955th Field Artillery Battalion achieved a peak rate of fire of 171.17 rounds per gun.[5]

NOTES

[4] The US artillery at Dom Bütgenbach peaked on 21 December 1944 when a total of 210 divisional and corps pieces fired over 10,000 rounds in support of the 1st Division’s 26th Infantry.

[5] Data collected on German rates of fire are fragmentary, but appear to be similar to that of the American Army in World War ll. An article on artillery rates of fire that explores the data in more detail will be forthcoming in a future issue of this newsletter. [NOTE: This article was not completed or published.]

Notes to Table I.

[8] The data were found in reports of the 1st Tank Army (Fond 299, Opis‘ 3070, Delo 226). Obvious math errors in the original document have been corrected (the total lost column did not always agree with the totals by cause). The total participated column evidently reflected the starting strength of the unit, plus replacement vehicles. “Burned'” in Soviet wartime documents usually indicated a total loss, however it appears that in this case “burned” denoted vehicles totally lost due to direct fire antitank weapons. “Breakdown” apparently included both mechanical breakdown and repairable combat damage.

[9] Note that the brigade report (Fond 3304, Opis‘ 1, Delo 24) contradicts the army report. The brigade reported that a total of 28 T-34s were lost (9 to aircraft and 19 to “artillery”) and one T-60 was destroyed by a mine. However, this report was made on 11 July, during the battle, and may not have been as precise as the later report recorded by 1st Tank Army. Furthermore, it is not as clear in the brigade report that “artillery” referred only to indirect fire HE and not simply lo both direct and indirect fire guns.

Artillery Effectiveness vs. Armor (Part 5-Summary)

The effectiveness of artillery against exposed personnel and other “soft” targets has long been accepted. Fragments and blast are deadly to those unfortunate enough to not be under cover. What has also long been accepted is the relative—if not total—immunity of armored vehicles when exposed to shell fire. In a recent memorandum, the United States Army Armor School disputed the results of tests of artillery versus tanks by stating, “…the Armor School nonconcurred with the Artillery School regarding the suppressive effects of artillery…the M-1 main battle tank cannot be destroyed by artillery…”

This statement may in fact be true,[1] if the advancement of armored vehicle design has greatly exceeded the advancement of artillery weapon design in the last fifty years. [Original emphasis] However, if the statement is not true, then recent research by TDI[2] into the effectiveness of artillery shell fire versus tanks in World War II may be illuminating.

The TDI search found that an average of 12.8 percent of tank and other armored vehicle losses[3] were due to artillery fire in seven eases in World War II where the cause of loss could be reliably identified. The highest percent loss due to artillery was found to be 14.8 percent in the case of the Soviet 1st Tank Army at Kursk (Table II). The lowest percent loss due to artillery was found to be 5.9 percent in the case of Dom Bütgenbach (Table VIII).

The seven cases are split almost evenly between those that show armor losses to a defender and those that show losses to an attacker. The first four cases (Kursk, Normandy l. Normandy ll, and the “Pocket“) are engagements in which the side for which armor losses were recorded was on the defensive. The last three cases (Ardennes, Krinkelt. and Dom Bütgenbach) are engagements in which the side for which armor losses were recorded was on the offensive.

Four of the seven eases (Normandy I, Normandy ll, the “Pocket,” and Ardennes) represent data collected by operations research personnel utilizing rigid criteria for the identification of the cause of loss. Specific causes of loss were only given when the primary destructive agent could be clearly identified. The other three cases (Kursk, Krinkelt, and Dom Bütgenbach) are based upon combat reports that—of necessity—represent less precise data collection efforts.

However, the similarity in results remains striking. The largest identifiable cause of tank loss found in the data was, predictably, high-velocity armor piercing (AP) antitank rounds. AP rounds were found to be the cause of 68.7 percent of all losses. Artillery was second, responsible for 12.8 percent of all losses. Air attack as a cause was third, accounting for 7.4 percent of the total lost. Unknown causes, which included losses due to hits from multiple weapon types as well as unidentified weapons, inflicted 6.3% of the losses and ranked fourth. Other causes, which included infantry antitank weapons and mines, were responsible for 4.8% of the losses and ranked fifth.

[3] The percentage loss by cause excludes vehicles lost due to mechanical breakdown or abandonment. lf these were included, they would account for 29.2 percent of the total lost. However, 271 of the 404 (67.1%) abandoned were lost in just two of the cases. These two cases (Normandy ll and the Falaise Pocket) cover the period in the Normandy Campaign when the Allies broke through the German defenses and began the pursuit across France.

Artillery Survivability In Modern Combat

[This piece was originally published on 17 July 2017.]

Much attention is being given in the development of the U.S. joint concept of Multi-Domain Battle (MDB) to the implications of recent technological advances in long-range precision fires. It seems most of the focus is being placed on exploring the potential for cross-domain fires as a way of coping with the challenges of anti-access/area denial strategies employing long-range precision fires. Less attention appears to be given to assessing the actual combat effects of such weapons. The prevailing assumption is that because of the increasing lethality of modern weapons, battle will be bloodier than it has been in recent experience.

I have taken a look in previous posts at how the historical relationship identified by Trevor Dupuy between weapon lethality, battlefield dispersion, and casualty rates argues against this assumption with regard to personnel attrition and tank loss rates. What about artillery loss rates? Will long-range precision fires make ground-based long-range precision fire platforms themselves more vulnerable? Historical research suggests that trend was already underway before the advent of the new technology.

In 1976, Trevor Dupuy and the Historical Evaluation and Research Organization (HERO; one of TDI’s corporate ancestors) conducted a study sponsored by Sandia National Laboratory titled “Artillery Survivability in Modern War.” (PDF) The study focused on looking at historical artillery loss rates and the causes of those losses. It drew upon quantitative data from the 1973 Arab-Israel War, the Korean War, and the Eastern Front during World War II.

Conclusions

1. In the early wars of the 20th Century, towed artillery pieces were relatively invulnerable, and they were rarely severely damaged or destroyed except by very infrequent direct hits.

2. This relative invulnerability of towed artillery resulted in general lack of attention to the problems of artillery survivability through World War II.

3. The lack of effective hostile counter-artillery resources in the Korean and Vietnam wars contributed to continued lack of attention to the problem of artillery survivability, although increasingly armies (particularly the US Army) were relying on self-propelled artillery pieces.

4. Estimated Israeli loss statistics of the October 1973 War suggest that because of size and characteristics, self-propelled artillery is more vulnerable to modern counter-artillery means than was towed artillery in that and previous wars; this greater historical physical vulnerability of self-propelled weapons is consistent with recent empirical testing by the US Army.

5. The increasing physical vulnerability of modern self-propelled artillery weapons is compounded by other modern combat developments, including:

a. Improved artillery counter-battery techniques and resources;
b. Improved accuracy of air-delivered munitions;
c..increased lethality of modern artillery ammunition; and
d. Increased range of artillery and surface-to-surface missiles suitable for use against artillery.

6. Despite this greater vulnerability of self-propelled weapons, Israeli experience in the October war demonstrated that self-propelled artillery not only provides significant protection to cannoneers but also that its inherent mobility permits continued effective operation under circumstances in which towed artillery crews would be forced to seek cover, and thus be unable to fire their weapons. ‘

7. Paucity of available processed, compiled data on artillery survivability and vulnerability limits analysis and the formulation of reliable artillery loss experience tables or formulae.

8. Tentative analysis of the limited data available for this study indicates the following:

a. In “normal” deployment, percent weapon losses by standard weight classification are in the following proportions:

b. Towed artillery losses to hostile artillery (counterbattery) appear in general to very directly with battle intensity (as measured by percent personnel casualties per day), at a rate somewhat less than half of the percent personnel losses for units of army strength or greater; this is a straight-line relationship, or close to it; the stronger or more effective the hostile artillery is, the steeper the slope of the curve;

c. Towed artillery losses to all hostile anti-artillery means appears in general to vary directly with battle intensity at a rate about two-thirds of the-percent personnel losses for units of army strength or greater; the curve rises slightly more rapidly in high intensity combat than in normal or low-intensity combat; the stronger or more effective the hostile anti-artillery means (primarily air and counter-battery), the steeper the slope of the curve;

d. Self-propelled artillery losses appear to be generally consistent with towed losses, but at rates at least twice as great in comparison to battle intensity.

9. There are available in existing records of US and German forces in World war II, and US forces in the Korean and Vietnam Wars, unit records and reports that will permit the formulation of reliable artillery loss experience tables and formulae for those conflicts; these, with currently available and probably improved, data from the Arab-Israeli wars, will permit the formulation of reliable artillery loss experience tables and formulae for simulations of modern combat under current and foreseeable future conditions.

The study caveated these conclusions with the following observations:

Most of the artillery weapons in World War II were towed weapons. By the time the United States had committed small but significant numbers of self-propelled artillery pieces in Europe, German air and artillery counter-battery retaliatory capabilities had been significantly reduced. In the Korean and Vietnam wars, although most American artillery was self-propelled, the enemy had little counter-artillery capability either in the air or in artillery weapons and counter-battery techniques.

It is evident from vulnerability testing of current Army self-propelled weapons, that these weapons–while offering much more protection to cannoneers and providing tremendous advantages in mobility–are much more vulnerable to hostile action than are towed weapons, and that they are much more subject to mechanical breakdowns involving either the weapons mountings or the propulsion elements. Thus there cannot be a direct relationship between aggregated World War II data, or even aggregated Korean war or October War data, and current or future artillery configurations. On the other hand, the body of data from the October war where artillery was self-propelled is too small and too specialized by environmental and operational circumstances to serve alone as a paradigm of artillery vulnerability.

Despite the intriguing implications of this research, HERO’s proposal for follow on work was not funded. HERO only used easily accessible primary and secondary source data for the study. It noted much more primary source data was likely available but that it would require a significant research effort to compile it. (Research is always the expensive tent-pole in quantitative historical analysis. This seems to be why so little of it ever gets funded.) At the time of the study in 1976, no U.S. Army organization could identify any existing quantitative historical data or analysis on artillery losses, classified or otherwise. A cursory search on the Internet reveals no other such research as well. Like personnel attrition and tank loss rates, it would seem that artillery loss rates would be another worthwhile subject for quantitative analysis as part of the ongoing effort to develop the MDB concept.
