SUMMARY: CNAS National Security Conference

By: Kiara Earle and Trevor Parkes

On Wednesday June 11, employees of various national security focused companies, agencies, and armed forces branches packed in alongside academics, enthusiasts and students for the eighth annual Center for New American Security’s National Security Conference.  The crowd talked excitedly around the coffee and pastry table in anticipation of the day including panels and presentations on topics from U.S. leadership in the world to the future of the defense industry to robotics on the battlefield, all headlined by addresses from Congressman Paul Ryan and National Security Advisor Susan Rice.

What Does the World Expect from U.S. Leadership?

The opening panel featured Dr. Zhu Feng, German Diplomat Wolfgang Ischinger, and General Amos Yadlin (Ret.), with Judy Woodruff as moderator.  The panel inquired about the role of the U.S. in the world, what it should be doing in the years to come, and strategies of implementation for its foreign policy.

Dr. Feng spoke on the positives of United States leadership in the East Asian region, and the threat of a rising China.  Much of the media proclaims China as the greatest modern rival to U.S. primacy, but the U.S. should not be too concerned because China has little soft power, and is “free riding” on U.S. primacy.

Expressing the sentiment that “America is not listening to us, but listening in on us,” Diplomat Ischinger emphasized the necessity to re-establish trust between Europe and the U.S.  As many of the international institutions experience gridlock, the U.S. should lead an initiative to reform these institutions.

General Yadlin commented on U.S. leadership’s hesitance and critiqued its effect on U.S. diplomacy.  According to the General, diplomacy becomes ineffective once military action is taken off the table.  However, military action should not include occupation of a country.  For U.S. diplomacy to be more effective, U.S. leadership needs to gain a clear direction.

Each panelist was very insightful, and their contributions to the panel gave a clear regional perspective of U.S. leadership continuing, at least, for the next few years.

A Strategy for Renewal

Congressman Paul Ryan said the United States must rebuild lost credibility by improving three sources of our strength: our allies, our military, and our economy.  U.S. credibility with our allies has been shaken by President Obama’s announcement that troops will leave Afghanistan in 2016 and recognition of the Palestinian Authority government including Hamas. We should be pressing NATO countries to invest in a coordinated set of capabilities, make a stand in Eastern Europe, and beef up our Pacific fleet with the refueled U.S.S. George Washington. In regards to the military, the Budget Control Act made progress against the deficit but slashed the defense budget, leaving obsolete equipment and a lack of funding to build technology for tomorrow’s threats.

To strengthen our economy, and therefore our military, we must reform entitlements, balance the budget, and pay off the national debt which is “the greatest threat to American leadership.” Congressman Ryan commented on China’s aggression; China “isn’t trying to bend the rules—it’s trying to rewrite them altogether. It’s stealing our intellectual property. It’s attacking our companies. It’s promoting crony capitalism.” The US has to improve ties with China’s neighbors and show China “it doesn’t pay to break the rules.”  In conclusion Congressman Ryan described himself as Jack Kemp once did, a heavily armed dove, and proclaimed “we constantly renew our strength so we don’t have to use it.”[i]

Creative Disruption: Strategy, Technology and the Future Defense Industry

Panelists, former Deputy Secretary of Defense William J. Lynn III and Admiral James Stavridis (Ret.), with Ben FitzGerald moderating, discussed the future of the defense industry.  The message this panel sent to its audience is that the world is changing, and the defense industry, whether it wants to or not, is changing with it.

Violent extremism and religious warfare increasingly threaten global security as rogue states and terrorist groups are changing warfare itself.  The Department of Defense needs to reform in order to confront these changes.  Admiral Stavridis expressed that some of these changes need to occur by investing more in DoD people.  By investing in language and culture, people within the DoD should be better equipped to approach complex security challenges.

Former Deputy Secretary Lynn shared the same sentiment of reform.  Currently, the U.S. is superior in many fields, such as cyber.  The heavy dependence on cyber technology, however, has created a major vulnerability to critical infrastructure that the U.S. government needs to address.  Evolving strategic challenges threaten U.S. infrastructure, as well as its competitive advantage.

Strategic Risk and Military Power: A Briefing to the Next President

Panelists, General James E. Cartwright (Ret.), CNAS CEO Michele Flournoy, and Roger Zakheim, briefed the 45th president on the strategic risks that will be faced in 2016.  Each panelist presented their reports on how the president should strategically approach new risks and challenges.  The common theme from their reports emphasized ensuring the U.S. would be better equipped with confronting threats posed by non-state actors.  These plans would require not only reform in the DoD’s capabilities and structure, but a more comprehensive economic strategy set by Congress.

Risk and Opportunity in Indo-Pacific Asia

Ambassador R. Nicholas Burns, Dr. David F. Gordon, Stephanie Kleine-Ahlbrandt, Vikram J. Singh, and General James D. Thurman (Ret.) gathered together with moderator Dr. Patrick Cronin to discuss the risk and opportunities that exist for the U.S. in Indo-Pacific Asia.  The instability of the DPRK was discussed, along with the economic rise of China in the region.  China, however, was also discussed as an opportune partner for the U.S.  The panel touched on ASEAN, its potential for highly effective regional governance, and the inefficiencies that limit the organization.  Each panelist shone a different light highlighting various relationships that affect the region and U.S. interests.  The panel collectively expressed that the U.S. has an important role within the region, but this role must work to keep the peace without trying to dominate other countries.

Keynote Address by Ambassador Susan Rice

National Security Advisor Susan Rice echoed President Obama’s West Point Speech and explained that it was not a matter of if the United States would lead the world, but how it would. The U.S. must continue to take a leading role in mobilizing coalitions to handle the toughest problems in the international community such as bringing economic sanctions down on Russia in response to its annexation of Crimea, updating our defense strategies with South Korea and Japan, funding counter-terrorism efforts worldwide, sending humanitarian aid to Syria, and working on a nuclear agreement with Iran.  In addition, National Security Advisor Rice touched on a wide range of issues from stopping disease outbreaks, reversing climate change, and protecting internet security and openness.

Mobilizing coalitions also allows for expanding shared prosperity through trade partnerships, private investment, and achieving the Millennium Development Goals. Finally, coalitions help reinforce universal values that protect human rights, dignity, and health and pressure abusive countries.  National Security Advisor Rice ended by saying “we are stronger still when we mobilize the world on behalf of our common security and common humanity…and that is what’s required to shape a new chapter of American leadership.”[ii]

Visualizing Today’s Veterans Population and Forecasting the Issues of Tomorrow

If the Veterans Administration had seen CNAS Director of the Military, Veterans, and Society Program Phillip Carter’s visualization of the US Veterans Population it might not be a thorn in the Obama administration’s side today.  Director Carter’s project uses data and calculations to show where the veterans population lives, a population projection, what area gets what funding, and how the projection can change given the chance of future conflict. These visualizations show that some counties receive way less or more funding than needed and can help make predictions on what services will be needed in the future.  Given that the VA is under intense scrutiny, Vietnam veterans are hitting the retirement age, and a decade long war is winding down, this information is going to become invaluable as the country moves forward.

Robotics on the Battlefield: The Coming Swarm

Featuring a display of unmanned aircraft, underwater and surface vehicles, and land robotic units taking part in a military operation the Project Director of CNAS’ 20YY Warfare Initiative Paul Scharre laid out the future of robotics on the battlefield.  If a pilot found himself in a fight for his life a swarm of unmanned aircraft could tip the scales.  If a carrier was targeted by long range missiles unmanned vessels carrying anti-missile rockets could protect the ship.  If a landing force faced opposition unmanned robotic units could take the beach without suffering casualties.  Although these projects are still a few years and millions of dollars from deploying, swarming robotics may be the way to overwhelm future challenges with superior numbers and technology while avoiding human casualties.

Energy, Iran and the Future of Gulf Security

The panel of the Honorable Stephen Hadley, CNAS Director of Energy, Environment and Security Program Elizabeth Rosenberg, and Ambassador Dennis Ross discussed continued American involvement in the Middle East. As long as it produces the best crude oil in the world, terrorist groups threaten peace, and Iran defends its nuclear program, America will have a reason to invest interest.  Oil levels worldwide will fluctuate as the shale boom starts and will be exacerbated if Libya and Iran are able to export on the world market.  As Syria is in civil war and Iraq is primed for sectarian violence ISIS has carved out a state for itself, threatening the region.  Looming large is the fact that a nuclear agreement with Iran may not be reached any time soon.   Stability in the Middle East is not in the immediate future and, although the Obama Administration has heralded a Pivot to Asia, it should be prepared to continue its Middle East focus simultaneously.

China’s Conventional Strikes against the U.S. Homeland

Bruce Sugden brings us this dour scenario, representing the last of our “Sacking of Rome” series.    

With its precision-strike complex, the United States has conducted conventional strikes on enemy homelands without fear of an in-kind response. Foreign military developments, however, might soon enable enemy long-range conventional strikes against the U.S. homeland. China’s January 2014 test of a hypersonic vehicle, which was boosted by an intercontinental ballistic missile (ICBM), suggests that it has designs on deploying a long-range conventional strike capability akin to the U.S. prompt global strike development effort.[1] If China pushes forward with deployment of a robust long-range conventional strike capability, within 20 years Americans could expect to see the U.S. homeland come under kinetic attack as a result of U.S. intervention in a conflict in the western Pacific region. With conventional power projection capabilities of its own and a secure second-strike nuclear force, China might replace the United States as the preponderant power in East Asia.

The implication of Chinese long-range strike is that U.S. military assets and supporting infrastructure in the deep rear, an area that is for the most part undefended, will be vulnerable to enemy conventional strikes—a vulnerability that U.S. forces have not had to deal with since the Second World War. Furthermore, China would be tempted to leverage its long-range strike capabilities against vital non-military assets, such as power generation facilities and network junctions, major port facilities, and factories that would produce munitions and parts to sustain a protracted U.S. military campaign. The American people and the U.S. government will have to prepare themselves for a type of warfare that they have never experienced before.

Emerging Character of the Precision-Strike Regime

            What we have become familiar with in the conduct of conventional precision-strike warfare since 1991 has been the U.S. use of force in major combat operations. The U.S. precision-strike complex is a battle network, or system, of intelligence surveillance, and reconnaissance (ISR) sensors designed to detect and track enemy forces and facilities, weapons systems to deliver munitions over extended range (e.g., bombers from the U.S. homeland) with high accuracy, and connectivity to command, control, communications, and computers (C4) organized to compress the time span between detection of a target and engagement of that target.[2] Since the 1990s weapons delivery accuracies have been enhanced by linking the guidance systems with a space-based positioning, navigation, and timing (PNT) system.

            China’s People’s Liberation Army (PLA) has studied the employment of the U.S. precision-strike complex and has been building its own for years. Since the 1990s, China has been increasing the number of deployed short- and medium-range ballistic missiles, many of which U.S. observers tend to believe are armed with conventional warheads.[3] China has also been improving the accuracies of its missiles by linking many of them to its space-based PNT system, Beidou. In addition, the PLA has been deploying several types of land-attack and anti-ship cruise missile systems.[4] These weapons systems are part of a layered defense approach that the PLA has adopted to keep foreign military forces, mainly U.S. forces, outside of China’s sphere of interest.

There are indications that China is expanding its precision-strike complex to reach targets further away from Chinese territory and waters. First, as the most recent DOD report on Chinese military power notes, China is developing an intermediate-range (roughly 3,000-5,000 kilometers) ballistic missile that could reach targets in the Second Island Chain, such as U.S. military facilities on Guam, and might also be capable of striking mobile targets at sea, such as U.S. aircraft carriers.[5] Second, the PLA Air Force has developed the H-6K bomber, which might have a combat radius of up to 3,500 kilometers and be able to carry up to six land-attack cruise missiles.[6] Third, as mentioned above, China has tested a hypersonic vehicle using an ICBM.

China’s Interest in Hypersonic Vehicles

            In the previous decade, one American observer of the Chinese military noted that the Chinese defense industry was showing interest in developing long-range precision strike capabilities, including intercontinental-range hypersonic cruise missiles.[7] Drawing from Chinese open-source literature, Lora Saalman believes that “China is developing such systems not simply to bolster its regional defense capabilities at home, but also to erode advantages of potential adversaries abroad, whether ballistic missile defense or other systems.”[8] Moreover, compared with the Chinese literature on kinetic intercept technologies, with “high-precision and high-speed weaponry, the Chinese vision is becoming much clearer, much faster. Beyond speed of acquisition, the fact that nearly one-half of the Chinese studies reviewed cover long-range systems and research low-earth orbit, near space, ballistic trajectories, and reentry vehicles suggests that China’s hypersonic, high-precision, boost-glide systems will also be increasingly long in range.”[9]

            China’s attraction to hypersonic technologies seems to be related to U.S. missile defenses.[10] As many U.S. experts have believed since the 1960s, when the United States first conducted research and development on hypersonic vehicles, such delivery systems provide the speed and maneuverability to circumvent missile defenses.[11] These characteristics enable hypersonic vehicles to complicate missile tracking and engagement radar systems’ attempts to obtain a firing solution for interceptors.

How a Future U.S.-China Conflict Might Unfold

            Although we cannot be certain about how a future military conflict between the United States and China might develop, the ongoing debate over the U.S. Air-Sea Battle concept suggests that alternative approaches to employing U.S. military force against China could persuade the Chinese leadership to order conventional strikes against targets in the U.S. homeland. On the one hand, in response to PLA aggression in the East or South China Seas, an aggressive forward U.S. military posture would include conventional strikes against targets on the Chinese mainland, such as air defense systems, airfields and missile operating locations from which PLA attacks originated, C4 and sensor nodes linked to PLA precision-strike systems, and PLA Navy (PLAN) facilities and ships.[12] These strikes would threaten to weaken PLA military capabilities and raise the ire of the Chinese public and leadership. Even assuming that China opened hostilities with conventional missile strikes against U.S. forces at sea and on U.S. and allied territories (Guam and Japan, respectively) to forestall operations against the PLA, the Chinese public and the PLA might pressure the leadership to respond with similar strikes against the U.S. homeland.

            A less aggressive U.S. military posture, on the other hand, such as implementation of a distant blockade, would focus military resources on choking off China’s importation of energy supplies and denying PLA forces access to the air and seas within the First Island Chain.[13] While this approach might play to the asymmetric advantages of the U.S. military over the PLA, the threat of being cut off from its seaborne energy supplies over an extended period of time might convince Beijing that it needed to reach out and touch the United States in ways that might quickly persuade it to end the blockade.

Targets of Chinese Long-Range Conventional Strikes

            Although many recent PLA doctrinal writings point to the use of conventional ballistic missiles in missions to support combat operations by PLA ground, air, naval, and information operations units, a stand-alone missile campaign could be designed to conduct selective strikes against critical targets.[14] Ron Christman believes that the “goals of such a warning strike would be to display China’s military strength and determination to prevent an ongoing war from escalating, to protect Chinese targets, to limit damage from an adversary’s attack, or to coerce the enemy into yielding to Chinese interests.”[15]

            The PLA’s ideal targets might include low density/high demand military assets, major power generation sites, key economic and political centers, and war-supporting industry.[16] More specifically, with U.S. forces conducting strikes against PLA assets on mainland China, sinking PLAN ships at sea, and blocking energy shipments to China, PLA military planners might be tempted to strike particular fixed targets to weaken U.S. power projection and political will: Whiteman Air Force Base, home of the B-2A bombers; naval facilities and pierside aircraft carriers at San Diego and Kitsap; facilities and pierside submarines at Bangor; space launch facilities at Vandenberg Air Force Base and Cape Canaveral; Lockheed Martin’s joint air-to-surface stand-off missile (JASSM) factory in Troy, Alabama; Travis Air Force Base, where many transport aircraft are based; and major oil refineries in Texas to squeeze the U.S. economy.

Effects of Conventional Strikes against the U.S. Homeland

            It is plausible that Chinese conventional precision strikes against targets in the U.S. homeland would set in train several operational and strategic effects. First, scarce military resources could be damaged and rendered inoperable for significant periods of time, or destroyed. Whether at Whiteman Air Force Base or the west coast naval bases, such losses would impair the conduct of U.S. operations against China. Furthermore, damaged or destroyed munitions factories, logistics nodes, and space launch facilities would undermine the ability of the U.S. military to conduct a protracted war by replenishing forward-deployed forces and replacing lost equipment. The U.S. military might have to re-deploy significant numbers of forces from other regions, such as Europe and the Persian Gulf.

Second, the American people, if they believed that fighting in East Asia was not worth the cost of attacks against the homeland, might turn against the war effort and the politicians that supported it. Even if a majority of Americans were to remain steadfast in support of the war, however, public opinion would not protect critical assets from being struck by Chinese conventional precision strikes.

Third, the operational effects might sow doubt in the minds of U.S. allies about the survivability and effectiveness of the U.S. power projection chain, while American protests in the streets against the U.S. government would undermine allies’ confidence in the resolve of the United States. If the allies judged that the United States lacked the capability or the will to wage war across the Pacific Ocean against China, then they might accommodate China and cut military ties with the United States. The loss of these military alliances, moreover, could result in the disintegration of the international order that the United States has built and sustained with military might for decades.[17]

Fourth, facing damage from strikes against the homeland and perhaps lacking the conventional military means to defend its allies and achieve its war aims, the United States might have to choose between defeat in East Asia or escalation to the use of nuclear weapons to fulfill its security guarantees. U.S. nuclear strikes, of course, might elicit a Chinese nuclear response.

Measures to Mitigate the Effects of Conventional Strikes

            Three approaches come to mind that might mitigate the effects of conventional strikes and, perhaps, dissuade China from expending weapons against the U.S. homeland. The development of less costly but more advanced missile defense technologies that could be deployed in large quantities could protect critical assets. The technologies might remain beyond our grasp, however. Directed energy weapons, for example, would still need to find and track the incoming target for an extended period of time, and then maintain the laser beam on one point on the target to burn through it.[18]

            If missile guidance systems remained tied to space-based PNT in the 2030s, then ground-based jammers might be able to divert incoming hypersonic vehicles off course. Without accurate weapons delivery, the conventional warheads would be less effective against even soft targets. Future onboard navigation systems, however, might enable precise weapons deliveries that would be unaffected by jamming.[19]

            The final and possibly most effective approach takes a page from China’s playbook: disperse and bury key assets and provide hardened, overhead protection for parked aircraft and pierside ships.[20] Because burying some facilities would be cost prohibitive, another protective measure might be to construct hardened shelters (including top covers) around surface installations like industrial infrastructure and munitions factories (though this measure might be cost prohibitive as well).

            This preliminary discussion suggests that cost-effective remedies are infeasible over the next few years, yet the threat of distant conventional military operations extending to the U.S. homeland will likely continue to grow. Therefore, more comprehensive analysis of active and passive defenses as well as other forms of damage limitation is needed to enable senior leaders to make prudent investment decisions on defense and homeland security preparedness against the backdrop of a potential conflict between the United States and China.

Lessons from the Late Roman Army

Our “Sacking of Rome series continues” with a sixth installment!

The unfamiliar face of the late Roman Army (Photo courtesy of Britannia).

By Steven Wills

Most popular portrayals of the Roman Army focus on the collapse of the Republic, as in the HBO “Rome” series, or the classical “high” empire as illustrated by the Russell Crowe epic “Gladiator”.  In contrast to these theatrical efforts is the period of the  so-called “late” Roman Empire of 220 A.D. to the 600’s. It offers significant lessons in how not to manage the army of a great power. While there are many possible causes for the downfall of the Roman Empire and resultant Dark Ages, military historians generally agree that three specific actions of Roman elites in the late Empire specifically contributed to the Empire’s eventual collapse. Cutting the retirement benefits of a small professional force in favor of smaller taxes for the elite and greater benefits for the masses served only to weaken the desire of Roman citizens to serve.  When the Roman citizenry would not join in the numbers required to protect the Empire, Roman elites turned to conscription, which produced only disgruntled recruits, and mass recruitment of barbarian tribes such as the Goths, Visigoths and Vandals. These tribesmen could be paid less and did not require expansive pensions as an incentive to serve. The so-called “barbarization” of the Roman Army seriously weakened its core values, made it more likely to rebel against Roman authority, and ultimately brought disaster to the gates of Rome itself in 410 A.D. These three mistakes in the management of the late Roman Imperial Army should serve as a powerful warning to American elites seeking inexpensive solutions to the maintenance of American military power. While some military spending can always be reduced, a great power that seeks very low-cost solutions does so at its own peril.

The Roman Army began providing pensions to retiring soldiers during the fall of the Roman Republic in the late first century B.C. Competing Roman leaders such as Julius Caesar, his great rival Pompey Magnus, Caesar’s nephew Octavian, later known as Augustus Caesar, and his famous opponent Marc Antony all offered grand incentives to retain the loyalty of their soldiers. These promises often included financial rewards, exemption from taxes and grants of land from captured enemy territory. Augustus Caesar continued this practice  when he consolidated power in the first century A.D. and became virtual dictator of the Empire under the title of Princeps (first citizen).  Augustus reduced the Roman Army to a voluntary, professional force of approximately 150,000 active duty soldiers and a similar number of auxiliary troops.  A soldier who served 20-25  years of active military service (accounts vary) would be eligible for the honesto missio, or honorable discharge from military service. Similar benefits were provided for soldiers disabled in the line of duty and unable to return to service. The soldier was provided an exemption from Roman taxes, a plot of land and appropriate work animals, and often a job in the imperial administration of the territory in which they settled. Roman veterans could be recalled to active duty in case of emergency and often provided a reliable, loyal citizenry in newly conquered territories. As the Empire grew, successive leaders, now styled as Emperors widened the veteran benefits until the mid third century A.D. After this troubled period of revolts, barbarian attacks and economic downturn and collapse, Roman authorities gradually reduced pensions and lengthened the period of active service necessary to receive full credit for service. This appears to have been done to reduce taxes for wealthy Romans living in the provinces.  Record are fragmentary from the later empire, but at some point in the third century A.D., bronze tablets replaced parchment documents as official evidence of service due to the inability of veterans to get the benefits they deserved. In addition, the empire’s policy of “bread and circuses” (generous food benefits and cheap entertainment) seemed a much better deal for the average lower class Roman citizen rather than increasingly dangerous and unrewarded services in the late Roman Army. As a result of these changes it would appear that the average lower class Roman citizen, the historical pool for legionary recruitment was much less inclined to a military career.

As Roman citizen recruitment failed to provide enough troops to protect an increasingly threatened Empire, Roman elites turned to conscription and barbarian recruitment. Conscripts were often ineffective and actively avoided reporting for duty. Some maimed themselves to ensure they would be found unfit for service. Recruitment of barbarians however offered a low cost solution to the manpower drain on the Roman Army. German tribes fleeing from the vicious Huns were desperate for sanctuary within the Empire and Roman officials equally needed soldiers to resist invasions. They negotiated with tribal chiefs for the military service of whole tribes in return for farmland for the tribe within Roman borders. Unfortunately, unscrupulous Roman officials were happy to defraud the tribesmen of their promised land, or commit them into combat situations where the highest casualties resulted. Such actions bred intense distrust and contributed to a uneasy co-existence of Roman and tribesman within the empire’s borders.

Artist conception of a 5th century A.D. Visigoth warrior.

The Romans further weakened their “barbarized” Army by neglecting the “Romanization” of the new recruits. Since the city on the Tiber River first mounted military operations, it actively absorbed new soldiers from the ranks of its enemies. These new recruits were not only trained in Roman ways of war, but were culturally and constitutionally converted into Roman citizens. They eagerly embraced Roman baths, aqueducts, regular salaries,  and other aspects of Roman law and culture. While such a procedure was effective with small groups of new soldiers, whole tribes of new barbarian recruits actively resisted Romanization. Roman officials were either unable or frankly too lazy or disinterested to continue this long-running successful process. Instead, the Roman Army was “barbarized” and became more German than Roman. The rigorous individual and team training that had been the hallmark of Roman arms for centuries was allowed to degrade in order to more easily employ the cheaper barbarian forces.  The tribal contingents’  loyalties often swung between imperial employers and barbarian roots and culture. The Roman elite’s disdain for this force caused further tension and when the tribes were denied pay and food, they actively rebelled. This rebellion brought the Visigoth leader Alaric to the gates of Rome in 410 A.D. seeking food and payment for prior military service. When Roman elites refused, common people in Rome, fearing a long siege and starvation, opened the gates of the city to Alaric and his men. Then in turn sacked the city and destroyed or stole countless  works of art. They also seized most of the city’s gold and silver. The Western half of the Roman Empire never recovered from this disaster. It lingered on with greater barbarian influence until tribesmen deposed the last Western Roman Emperor Romulus Augustulus in 476 A.D. The Eastern Empire had suffered a similar devastating defeat at the hands of Goths in 378 A.D. Rather than continue to accept barbarian recruits, it purged its army of tribesmen and returned to traditional Roman methods of training. In contrast with the west, this Eastern Empire endured for nearly another 1000 years. In summation, the Roman attempt to employ cheap alternatives for defense was an unmitigated disaster.

What can the United States learn from the example of the late Roman Empire? First, the maintenance of a professional force requires a generous pension system in order to maintain a steady supply of proficient recruits. According to former Chairman of the Joint Chiefs of Staff Admiral Mike Mullen in 2011, only 7-11% of  all military personnel complete 20 or more years of service and become eligible for a pension. Given that only 1% of Americans even serve in uniform, is a well funded U.S. military pension system such a great price to ensure a steady supply of recruits to serve the military needs to the Republic?  Reduced benefits may convince many Americans, as it did Romans, that long-term military service is not worth the low pay and arduous conditions involved to attain an increasingly modest pension.

Distributing smaller benefit amounts to a wider percentage of the active duty force, or worse yet, paying larger benefits only to those who served in combat will likely weaken the force cohesion and generate needless class struggle within the ranks. The Romans attempted similar measures by paying barbarians less than purely Roman forces and price was a loss of cohesiveness and team-building within the ranks.  In addition, rather than weld the fighting forces together in the shared experience of American culture, the services emphasize their differences by an over-emphasis on cultural diversity. The Romans Army of the high empire was extremely diverse and fielded units recruited from the British Isles to the deserts of Syria. It accommodated dozens of faiths and creeds within the shared Roman experience without the need to over-emphasize their differences. This successful system endured for centuries and served to insulate the legions from purely nationalistic strife.

The experience of the late Roman Army has much to offer the United States in the present. A professional military force needs a healthy pension structure.  Post service benefits are essential to the retention of a moderate-sized group of highly trained professionals necessary to wage modern war.  It is unwise to ignore the traditional sources of voluntary recruitment in search of lower-cost military solutions.  Finally, the shared experience of voluntary service to a strong national ideal united disparate nationalities within each Roman legion. Discarding this unifying, albeit expensive construct in favor of larger numbers of low cost conscripts and barbarians served only to hasten the empire’s end. The United States would do well to consider the fate of the late Roman Army as it seeks low cost, effective substitutes for current defense expenditures. In the end, a nation gets either what it pays or refuses to pay for in maintenance of national security.
