Military powerhouses such as the U.S. educate service cadets separately

The Ministry of National Defense recently announced a plan to dismantle the Army, Navy and Air Force academies and establish an integrated military academy at Jaundae in Daejeon. It cited sweeping policy rationales including force reductions amid a demographic cliff, preparation for advanced AI-driven warfare, the effects of a low birthrate and the transfer of wartime operational control. The government presents these pressures as interconnected reasons for redesigning the way Korea develops its future officer corps.

Strip away those arguments, however, and the central issue is simple. The choice between integration and independence comes down to which better serves national security and combat readiness: strengthening jointness or preserving service-specific operational expertise. In other words, the dispute is not primarily about buildings or administrative efficiency. It concerns how officers acquire the professional identity, judgment and expertise required to fight effectively before they are expected to operate jointly across services.

The stakes are high because relocating academy campuses and physically consolidating their facilities would amount to an effectively irreversible hardware change. By contrast, goals cited to justify integration, including stronger education for AI-era warfare and improvements in cadet recruitment and academic standards, can be addressed through software changes such as curriculum reform and greater investment regardless of whether the academies are merged. Training content can be revised as technology, recruiting conditions or operational requirements change. Physical consolidation, by contrast, would be far harder to reverse later in practice.

To understand the relationship between jointness and specialization, Korea should examine the U.S. debate over military academy reform after the Cold War and the legislation that followed. According to a Congressional Research Service report, CRS 97-217, Congress considered six alternatives amid intense pressure to cut defense spending, ranging from maintaining the existing academies to closing them and shifting officer training toward shorter programs such as the Reserve Officers' Training Corps and Officer Candidate School.

Yet consolidating the Army, Navy and Air Force academies into a single institution was not among the options. Even as Congress considered broad reforms, integration of the service academies was not treated as a major policy alternative.

U.S. reports and regulations point to three broad principles for developing elite officers.

First, service identity is formed through four years of immersion within each branch. U.S. Defense Department Instruction 1322.22 describes the academies as institutions that instill each service’s distinctive honor, traditions and values in cadets, who carry them throughout the force, making the academies a foundation for long-term readiness and service identity. The inner motivation to perform missions under extreme conditions on land, at sea or in the air grows from that sustained formation.

Second, domain expertise comes from an educational environment tailored to each service. A U.S. Government Accountability Office report, GAO 90-28, noted fundamental differences in the educational philosophies and faculty structures of the three academies. West Point emphasizes field leadership. The Naval Academy has relied heavily on civilian faculty while focusing on marine engineering and advanced weapons systems. The Air Force Academy develops the rapid technical judgment demanded by air operations. These are not merely curricular differences but reflect distinct forms of expertise and organizational culture. The educational environment is itself part of officer development.

Third, jointness is best developed among midcareer officers after they have accumulated field experience. The Goldwater-Nichols Act of 1986 and the 1989 Skelton Report established the principle that joint professional education should be pursued after officers gain meaningful operational experience. Genuine jointness can emerge only on a foundation of strong tactical and domain expertise.

The U.S. military therefore preserved independently operated service academies, developing branch expertise first and cultivating jointness later in officers’ careers.

The security environments and force sizes of the United States and Korea are not identical. Still, the basic officer development principle tested by the U.S. military, a leading practitioner of modern joint operations, is to establish service-specific expertise before developing jointness. That principle deserves consideration regardless of national scale.

Once changed, an officer training system will shape military readiness and culture for decades. What Korea needs now is not speed but rigorous verification. This is not an issue to be pushed through unilaterally. The government should take time, listen to a range of views and approach reform with an open mind.
