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.

TDI Friday Read: Multi-Domain Battle/Operations Doctrine

With the December 2018 update of the U.S. Army’s Multi-Domain Operations (MDO) concept, this seems like a good time to review the evolution of doctrinal thinking about it. We will start with the event that sparked the Army’s thinking about the subject: the 2014 rocket artillery barrage fired from Russian territory that devastated Ukrainian Army forces near the village of Zelenopillya. From there we will look at the evolution of Army thinking beginning with the initial draft of an operating concept for Multi-Domain Battle (MDB) in 2017. To conclude, we will re-up two articles expressing misgivings over the manner with which these doctrinal concepts are being developed, and the direction they are taking.

U.S. Army Doctrine and Future Warfare

 

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.

Comparing Force Ratios to Casualty Exchange Ratios

“American Marines in Belleau Wood (1918)” by Georges Scott [Wikipedia]

Comparing Force Ratios to Casualty Exchange Ratios
Christopher A. Lawrence

[The article below is reprinted from the Summer 2009 edition of The International TNDM Newsletter.]

There are three versions of force ratio versus casualty exchange ratio rules, such as the three-to-one rule (3-to-1 rule), as it applies to casualties. The earliest version of the rule as it relates to casualties that we have been able to find comes from the 1958 version of the U.S. Army Maneuver Control manual, which states: “When opposing forces are in contact, casualties are assessed in inverse ratio to combat power. For friendly forces advancing with a combat power superiority of 5 to 1, losses to friendly forces will be about 1/5 of those suffered by the opposing force.”[1]

The RAND version of the rule (1992) states that: “the famous ‘3:1 rule ’, according to which the attacker and defender suffer equal fractional loss rates at a 3:1 force ratio the battle is in mixed terrain and the defender enjoys ‘prepared ’defenses…” [2]

Finally, there is a version of the rule that dates from the 1967 Maneuver Control manual that only applies to armor that shows:

As the RAND construct also applies to equipment losses, then this formulation is directly comparable to the RAND construct.

Therefore, we have three basic versions of the 3-to-1 rule as it applies to casualties and/or equipment losses. First, there is a rule that states that there is an even fractional loss ratio at 3-to-1 (the RAND version), Second, there is a rule that states that at 3-to-1, the attacker will suffer one-third the losses of the defender. And third, there is a rule that states that at 3-to-1, the attacker and defender will suffer the same losses as the defender. Furthermore, these examples are highly contradictory, with either the attacker suffering three times the losses of the defender, the attacker suffering the same losses as the defender, or the attacker suffering 1/3 the losses of the defender.

Therefore, what we will examine here is the relationship between force ratios and exchange ratios. In this case, we will first look at The Dupuy Institute’s Battles Database (BaDB), which covers 243 battles from 1600 to 1900. We will chart on the y-axis the force ratio as measured by a count of the number of people on each side of the forces deployed for battle. The force ratio is the number of attackers divided by the number of defenders. On the x-axis is the exchange ratio, which is a measured by a count of the number of people on each side who were killed, wounded, missing or captured during that battle. It does not include disease and non-battle injuries. Again, it is calculated by dividing the total attacker casualties by the total defender casualties. The results are provided below:

As can be seen, there are a few extreme outliers among these 243 data points. The most extreme, the Battle of Tippennuir (l Sep 1644), in which an English Royalist force under Montrose routed an attack by Scottish Covenanter militia, causing about 3,000 casualties to the Scots in exchange for a single (allegedly self-inflicted) casualty to the Royalists, was removed from the chart. This 3,000-to-1 loss ratio was deemed too great an outlier to be of value in the analysis.

As it is, the vast majority of cases are clumped down into the corner of the graph with only a few scattered data points outside of that clumping. If one did try to establish some form of curvilinear relationship, one would end up drawing a hyperbola. It is worthwhile to look inside that clump of data to see what it shows. Therefore, we will look at the graph truncated so as to show only force ratios at or below 20-to-1 and exchange rations at or below 20-to-1.

Again, the data remains clustered in one corner with the outlying data points again pointing to a hyperbola as the only real fitting curvilinear relationship. Let’s look at little deeper into the data by truncating the data on 6-to-1 for both force ratios and exchange ratios. As can be seen, if the RAND version of the 3-to-1 rule is correct, then the data should show at 3-to-1 force ratio a 3-to-1 casualty exchange ratio. There is only one data point that comes close to this out of the 243 points we examined.

If the FM 105-5 version of the rule as it applies to armor is correct, then the data should show that at 3-to-1 force ratio there is a 1-to-1 casualty exchange ratio, at a 4-to-1 force ratio a 1-to-2 casualty exchange ratio, and at a 5-to-1 force ratio a 1-to-3 casualty exchange ratio. Of course, there is no armor in these pre-WW I engagements, but again no such exchange pattern does appear.

If the 1958 version of the FM 105-5 rule as it applies to casualties is correct, then the data should show that at a 3-to-1 force ratio there is 0.33-to-1 casualty exchange ratio, at a 4-to-1 force ratio a .25-to-1 casualty exchange ratio, and at a 5-to-1 force ratio a 0.20-to-5 casualty exchange ratio. As can be seen, there is not much indication of this pattern, or for that matter any of the three patterns.

Still, such a construct may not be relevant to data before 1900. For example, Lanchester claimed in 1914 in Chapter V, “The Principal of Concentration,” of his book Aircraft in Warfare, that there is greater advantage to be gained in modern warfare from concentration of fire.[3] Therefore, we will tap our more modern Division-Level Engagement Database (DLEDB) of 675 engagements, of which 628 have force ratios and exchange ratios calculated for them. These 628 cases are then placed on a scattergram to see if we can detect any similar patterns.

Even though this data covers from 1904 to 1991, with the vast majority of the data coming from engagements after 1940, one again sees the same pattern as with the data from 1600-1900. If there is a curvilinear relationship, it is again a hyperbola. As before, it is useful to look into the mass of data clustered into the corner by truncating the force and exchange ratios at 20-to-1. This produces the following:

Again, one sees the data clustered in the corner, with any curvilinear relationship again being a hyperbola. A look at the data further truncated to a 10-to-1 force or exchange ratio does not yield anything more revealing.

And, if this data is truncated to show only 5-to-1 force ratio and exchange ratios, one again sees:

Again, this data appears to be mostly just noise, with no clear patterns here that support any of the three constructs. In the case of the RAND version of the 3-to-1 rule, there is again only one data point (out of 628) that is anywhere close to the crossover point (even fractional exchange rate) that RAND postulates. In fact, it almost looks like the data conspires to make sure it leaves a noticeable “hole” at that point. The other postulated versions of the 3-to-1 rules are also given no support in these charts.

Also of note, that the relationship between force ratios and exchange ratios does not appear to significantly change for combat during 1600-1900 when compared to the data from combat from 1904-1991. This does not provide much support for the intellectual construct developed by Lanchester to argue for his N-square law.

While we can attempt to torture the data to find a better fit, or can try to argue that the patterns are obscured by various factors that have not been considered, we do not believe that such a clear pattern and relationship exists. More advanced mathematical methods may show such a pattern, but to date such attempts have not ferreted out these alleged patterns. For example, we refer the reader to Janice Fain’s article on Lanchester equations, The Dupuy Institute’s Capture Rate Study, Phase I & II, or any number of other studies that have looked at Lanchester.[4]

The fundamental problem is that there does not appear to be a direct cause and effect between force ratios and exchange ratios. It appears to be an indirect relationship in the sense that force ratios are one of several independent variables that determine the outcome of an engagement, and the nature of that outcome helps determines the casualties. As such, there is a more complex set of interrelationships that have not yet been fully explored in any study that we know of, although it is briefly addressed in our Capture Rate Study, Phase I & II.

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:

Japan’s Grand Strategy and Military Forces (IV)

Japanese Maritime Self Defense Force (JMSDF) Helicopter Destroyer JS Izumo. [Japan Ministry of Defense}

In my previous post, I took a look at the roots of the extremely close level of integration between the U.S. Navy (USN) and the Japanese Maritime Self-Defense Force (JMSDF). This post will look at new Japanese naval technology development efforts that compliment USN capabilities, which in turn further the common strategic interests of both countries.

While officially classed as a helicopter destroyer (per the doctrinal focus on anti-submarine warfare (ASW)), Izumo-class ships are aircraft carriers in many respects, not least by the image they project to other countries in the region. In March 2018, Japanese Defense Secretary Onodera announced that a study was underway to determine if the Izumo-class could embark F-35B fighters. This would give the JMSDF a similar capability to the U.S. Marine Corps’ (USMC) Amphibious Assault Ships or the Royal Navy’s (RN) new Queen Elizabeth class carrier, (65,000 tons empty). At only 27,000 tons fully loaded, the Izumo class is roughly half the size of U.S.S. America (44,971 tons, fully loaded).

The ability to generate air sorties at sea is a key capability that drives the acquisition of aircraft carriers. Generating stealth fighter sorties at sea gives a potent strike capability, which could conceivably be used to strike at North Korean missile launch facilities, for example. This contingency plan alone was enough to draw a diplomatic warning from Beijing.  Undeterred, the Japanese Defense Ministry just announced plans for F-35Bs to be purchased, as well as hypersonic missile capabilities.

Japan Maritime Self Defense Force (JMSDF) Soryu-class submarine Hakuryu (SS-503) arrives at Joint Base Pearl Harbor-Hickam for a scheduled port visit. (U.S. Navy/Cmdr. Christy Hagen/Released)

Another example of Japanese maritime power projection capability is the Soryu class submarine, who some have claimed is the “best submarine in the world” (Mizokami-san does good work at Japan Security Watch). Carrying up to 30 “fish,” the Soryu class’s Type 89 torpedo is a formidable weapon, not least of which is its maximum speed of 70 knots, which is faster than the U.S. Mk48 ADCAP torpedo’s 55 knots.

Starting this October, these subs will feature lithium-ion batteries, which can store about double the energy of a lead-acid battery for the same volume, and also offers a weight advantage. This enhances the Soryu’s power projection effectiveness, as the Japanese Ministry of Defense has recently announced deployments to the contested South China Sea.

While these are hailed as a first, it is more likely this was the initial announcement of such deployments, which probably have been ongoing for some time. There is a certain logic to parsing how these information releases are worded:

Demonstrating freedom of navigation, a Japanese submarine for the first time conducted drills in the South China Sea where China is constructing military facilities, according to Japanese government sources. The Defense Ministry secretly dispatched the Kuroshio, a Maritime Self-Defense Force submarine, which conducted anti-submarine drills on Sept. 13 with three MSDF destroyers that were on a long-term mission around Southeast Asia, they said. The ministry had conducted anti-submarine drills only in sea areas around Japan, they added. [emphasis added]

This says nothing about being the first deployment, only the first anti-submarine warfare (ASW) drill.

Mitsubishi Heavy Industries (MHI) has been awarded a contract by the Japanese MoD to build the first two of four ships of a new class of multirole frigate (seen here in computer-generated imagery) for the JMSDF. {Source: MHI]

In accordance with its 2018 National Defense Program Guidelines, Japan is also planning a new type of multi-role frigate. The JMSDF has announced plans “to introduce a new type of destroyer with minesweeping capabilities, with the aim of increasing the number of such vessels to 22 in the 2030s, sources said. In light of the intensifying activities of the Chinese Navy in the East China Sea, including around the Senkaku Islands in Okinawa Prefecture, the government aims to improve warning and surveillance capabilities.”

According to Jane’s,

[T]his new frigate class, which is intended to carry out surveillance missions in waters surrounding the Japanese archipelago, will be equipped with enhanced multirole capabilities, including the ability to conduct anti-mine warfare operations, which until now have been performed by the JMSDF’s ocean-going minesweepers. Armament on the frigates, each of which will be capable of embarking one helicopter as well as unmanned surface and underwater vehicles, is expected to include the navalized version of the Type-03 (also known as the ‘Chū-SAM Kai’) medium-range surface-to-air missile, a 5-inch (127 mm)/62-calibre gun, a vertical launch system, canister-launched anti-ship missiles, and a SeaRAM close-in weapon system.

From this, we can see that this weapon system is intended to keep the military balance in place in the home waters, more so than a power projection mission. The purpose for these capabilities becomes more clear when considering the investments by the Chinese People’s Liberation Army Navy (PLAN) in mine warfare. “Today, the evidence continues to mount that the employment of sea mines remains a core tenet of Chinese naval war-fighting doctrine.Andrew Erickson of the U.S. Naval War College has written a great white paper on the topic, entiled “Chinese Mine Warfare: A PLA Navy ‘Assassin’ s Mace’ Capability.”  More to follow on this in later posts!

Japan’s Grand Strategy and Military Forces (III)

[John Hopkins Applied Physics Lab]

In my previous post, I looked at the Japanese Maritime Self-Defense Force (JMSDF) basic strategic missions of defending Japan from maritime invasion and securing the sea lines of communication (SLOC). This post will examine the basis for JMSDF’s approach to those tasks.

In 2011, JMSDF Vice Admiral (Ret.) Yoji Koda published an excellent article in the Naval War College Review, entitled “A New Carrier Race?.” Two passages therefrom are particular relevant and illuminating:

In 1952, … the Japan Maritime Guard (JMG) was established as a rudimentary defense organization for the nation. The leaders of the JMG were determined that the organization would be a navy, not a reinforced coast guard. Most were combat-experienced officers (captains and below) of the former Imperial Japanese Navy, and they had clear understanding of the difference between a coast guard–type law-enforcement force and a navy. Two years later, the JMG was transformed into the JMSDF, and with leaders whose dream to build a force that had a true naval function was stronger than ever. However, they also knew the difficulty of rebuilding a real navy, in light of strict constraints imposed by the new, postwar constitution. Nonetheless, the JMSDF has built its forces and trained its sailors vigorously, with this goal in view, and it is today one of the world’s truly capable maritime forces in both quality and size.

This continuity with the World War II-era Imperial Japanese Navy (IJN) is evident in several practices. The JMSDF generally re-uses IJN names of for new vessels, as well as its naval ensign, the Kyokujitsu-ki or “Rising Sun” flag. This flag is seen by some in South Korea and other countries as symbolic of Japan’s wartime militarism. In October 2018, the JMSDF declined an invitation to attend a naval review held by the Republic of Korea Navy (ROKN) at Jeju island, due to a request that only national flags be flown at the event. This type of disagreement may have a material impact on the ability of the JMSDF and the ROKN, both allies of the United States, to jointly operate effectively.

Koda continued:

Since the founding of the Japan Self-Defense Force (JSDF) and within it the JMSDF, in 1954…the bases of Japan’s national security and defense are the capability of the JSDF and the Japanese-U.S. alliance… Thus the operational concept of the JSDF with respect to the U.S. armed forces has been one of complementary mission-sharing, in which U.S. forces concentrate on offensive operations, while the JSDF maximizes its capability for defensive operations. In other words, the two forces form what is known as a “spear and shield” relationship… [T]he JMSDF ensures that Japan can receive American reinforcements from across the Pacific Ocean, guarantees the safety of U.S. naval forces operating around Japan, and enables U.S. carrier strike groups (CSGs) to concentrate on strike operations against enemy naval forces and land targets…[so] the JMSDF has set antisubmarine warfare as its main task…ASW was made the main pillar of JMSDF missions. Even in the present security environment, twenty years after the end of the Cold War and the threat of invasion from the Soviet Union, two factors are unchanged—the Japanese-U.S. alliance and Japan’s dependence on imported natural resources. Therefore the protection of SLOCs has continued to be a main mission of the JMSDF.

It is difficult to overstate the degree to which the USN and JMSDF are integrated. The US Navy’s Seventh Fleet is headquartered in Yokosuka, Japan, where the U.S.S. Ronald Reagan, a Nimitz-class super carrier, is stationed. Historically, this position was filled by the U.S.S. George Washington, which is currently back in Virginia undergoing refueling and overhaul. According to the Stars and Stripes, she may return to Japan with a new air wing, incorporating the MQ-25A Stingray aerial refueling drones.

According to the Center for Naval Analysis (CNA), the USN has the following ships based in Japan:

  • Yokosuka (south of Tokyo, in eastern Japan)
    • One CVN (nuclear aircraft carrier), U.S.S. Ronald Reagan
    • One AGC (amphibious command ship), U.S.S. Blue Ridge
    • Three CG (guided missile cruisers)
    • Seven DDG (guided missile destroyers)
  • Sasebo (north of Nagasaki, in the southern island of Kyuushu)
    • One LHD (amphibious assault ship, multi-purpose), U.S.S. Bon Home Richard
    • One LPD (amphibious transport dock), U.S.S. Greenway
    • Two LSD (dock landing ship)
    • Four MCM (mine counter measure ship)

One example of this close integration is the JS Maya, a Guided Missile Destroyer (DDG), launched on 30 July 2018. The ship is currently outfitting and is expected to be commissioned in 2020. A notable feature is the Collective Engagement Capability (CEC) (see graphic above). CEC is a “revolutionary approach to air defense,” according to John Hopkins Applied Physics Lab (which is involved in the development), “it allows combat systems to share unfiltered sensor measurements data associated with tracks with rapid timing and precision to enable the [USN-JMSDF] battlegroup units to operate as one.”

Zhang Junshe, a senior research fellow at the China’s People’s Liberation Army Naval Military Studies Research Institute, expressed concern in Chinese Global Times about this capability for “potentially targeting China and threatening other countries… CEC will strengthen intelligence data sharing with the US…strengthen their [US and Japan] military alliance. From the US perspective, it can better control Japan… ‘Once absolute security is realized by Japan and the US, they could attack other countries without scruples, which will certainly destabilize other regions.’”

Japan’s Grand Strategy and Military Forces (II)

In my first post on Japan’s grand strategy, I examined its “free and open” Indo-Pacific policy and briefly reviewed its armed forces—nominally “self-defense forces (SDF)”—as well as the legal reasons for this euphemism, and the Japanese government’s plans to clarify this constitutional conundrum.

The next several posts in this series will focus on a general overview of the Japanese Maritime Self-Defense Force (JMSDF), why this branch is considered primary (or dominant), some history in terms of how it came to be, the current missions, defense concepts, current capabilities and how they have been envisioned, how they are deployed, and a look ahead about options under consideration.

According to an excellent article in the Naval War College Review by Toshi Yoshihara, “the Japanese often describe their key national characteristic in nautical terms, with the familiar notion that ‘Japan is a small island nation lacking resource endowments and is thus highly dependent upon seaborne commerce for its well-being.’”

A few key facts, according to Jane’s Defense: Sea Module:

  • Japan has the world’s seventh-largest Exclusive Economic Zone (EEZ).
  • Japan operates a large commercial fishing fleet of about 200,000 vessels.
  • 90% of Japan’s oil is shipped from the Middle East.
  • 60% of Japan’s food is imported by sea.

The JMSDF is therefore tasked with the fundamental naval missions of defending Japan from maritime invasion and securing the sea lines of communication (SLOC). A recent article in the Japan News, spelled out why SLOC protection is vital for Japan:

[T]he South China Sea is a key sea-lane for Japan. If it became necessary to take a detour around the South China Sea, the additional time and fuel costs are estimated to be 1½ days and $120,000 for travel via the Sunda Strait, and three days and $240,000 for travel via the Lombok Strait. Both of these straits can be perilous, with strong tidal currents, sunken ships and shoals. If either were to see a large increase in marine traffic, chaos is predicted to ensue.

We can see this concern clearly in the recent JMSDF exercise deployment through the South China Sea, the straits of Sunda and Malacca, and onwards to India.

[The Japan News (Yomiuri Shimbun)]

For Indo Southeast Asia Deployment 2018 (ISEAD18) from 26 August to 30 October 2018, JMSDF vessels JS Kaga (DDH 184), JS Inazuma (DD105), JS Suzutsuki (DD117), stopped at Subic Bay, Philippines; Jakarta, Indonesia; Colombo, Sri Lanka; Visakhapatnam, India; and Changi, Singapore. The exercise included naval various exercises with port call countries, as well as the British and U.S. navies. This activity yielded important agreements, such as the maritime surveillance pact between Japan and India to share information on Chinese ship locations.

Force Ratios in Conventional Combat

[This piece was originally posted on 16 May 2017.]

This post is a partial response to questions from one of our readers (Stilzkin). On the subject of force ratios in conventional combat….I know of no detailed discussion on the phenomenon published to date. It was clearly addressed by Clausewitz. For example:

At Leuthen Frederick the Great, with about 30,000 men, defeated 80,000 Austrians; at Rossbach he defeated 50,000 allies with 25,000 men. These however are the only examples of victories over an opponent two or even nearly three times as strong. Charles XII at the battle of Narva is not in the same category. The Russian at that time could hardly be considered as Europeans; moreover, we know too little about the main features of that battle. Bonaparte commanded 120,000 men at Dresden against 220,000—not quite half. At Kolin, Frederick the Great’s 30,000 men could not defeat 50,000 Austrians; similarly, victory eluded Bonaparte at the desperate battle of Leipzig, though with his 160,000 men against 280,000, his opponent was far from being twice as strong.

These examples may show that in modern Europe even the most talented general will find it very difficult to defeat an opponent twice his strength. When we observe that the skill of the greatest commanders may be counterbalanced by a two-to-one ratio in the fighting forces, we cannot doubt that superiority in numbers (it does not have to more than double) will suffice to assure victory, however adverse the other circumstances.

and:

If we thus strip the engagement of all the variables arising from its purpose and circumstance, and disregard the fighting value of the troops involved (which is a given quantity), we are left with the bare concept of the engagement, a shapeless battle in which the only distinguishing factors is the number of troops on either side.

These numbers, therefore, will determine victory. It is, of course, evident from the mass of abstractions I have made to reach this point that superiority of numbers in a given engagement is only one of the factors that determines victory. Superior numbers, far from contributing everything, or even a substantial part, to victory, may actually be contributing very little, depending on the circumstances.

But superiority varies in degree. It can be two to one, or three or four to one, and so on; it can obviously reach the point where it is overwhelming.

In this sense superiority of numbers admittedly is the most important factor in the outcome of an engagement, as long as it is great enough to counterbalance all other contributing circumstance. It thus follows that as many troops as possible should be brought into the engagement at the decisive point.

And, in relation to making a combat model:

Numerical superiority was a material factor. It was chosen from all elements that make up victory because, by using combinations of time and space, it could be fitted into a mathematical system of laws. It was thought that all other factors could be ignored if they were assumed to be equal on both sides and thus cancelled one another out. That might have been acceptable as a temporary device for the study of the characteristics of this single factor; but to make the device permanent, to accept superiority of numbers as the one and only rule, and to reduce the whole secret of the art of war to a formula of numerical superiority at a certain time and a certain place was an oversimplification that would not have stood up for a moment against the realities of life.

Force ratios were discussed in various versions of FM 105-5 Maneuver Control, but as far as I can tell, this was not material analytically developed. It was a set of rules, pulled together by a group of anonymous writers for the sake of being able to adjudicate wargames.

The only detailed quantification of force ratios was provided in Numbers, Predictions and War by Trevor Dupuy. Again, these were modeling constructs, not something that was analytically developed (although there was significant background research done and the model was validated multiple times). He then discusses the subject in his book Understanding War, which I consider the most significant book of the 90+ that he wrote or co-authored.

The only analytically based discussion of force ratios that I am aware of (or at least can think of at this moment) is my discussion in my upcoming book War by Numbers: Understanding Conventional Combat. It is the second chapter of the book: https://dupuyinstitute.dreamhosters.com/2016/02/17/war-by-numbers-iii/

In this book, I assembled the force ratios required to win a battle based upon a large number of cases from World War II division-level combat. For example (page 18 of the manuscript):

I did this for the ETO, for the battles of Kharkov and Kursk (Eastern Front 1943, divided by when the Germans are attacking and when the Soviets are attacking) and for PTO (Manila and Okinawa 1945).

There is more than can be done on this, and we do have the data assembled to do this, but as always, I have not gotten around to it. This is why I am already considering a War by Numbers II, as I am already thinking about all the subjects I did not cover in sufficient depth in my first book.
