Korean Leadership Set to Expand in Combined Command After OPCON Transfer
The Korea-U.S. Combined Forces Command is expected to retain its integrated structure after Seoul regains wartime operational control, with a Korean four-star general taking command and a U.S. general serving as deputy. Questions remain about senior staff assignments and the Korean commander's authority over U.S. forces.
South Korea is expected to assume a larger leadership role in the Korea-U.S. Combined Forces Command after the transfer of wartime operational control, while preserving the alliance’s existing integrated command structure. The anticipated arrangement would place a Korean four-star general at the head of the command and a U.S. general in the deputy position.
Seoul and Washington have disclosed that they reached a provisional organizational plan for the command after the transfer, although they have not publicly detailed how responsibilities below the commander will be divided. The structure is due to be finalized during the Full Mission Capability assessment, the final stage of a three-phase evaluation process for the transfer.
Gen. Kim Seong-min, the command’s current deputy commander, told lawmakers during a parliamentary audit that the organizational plan remains a draft. He also rejected suggestions that the Combined Forces Command would be dissolved once operational control changes hands.
The command is currently led by a U.S. four-star general, with a Korean four-star general serving as deputy. Its combined staff includes officers from both countries who plan and direct joint operations. Established in 1978, it has long functioned as the principal wartime headquarters for coordinating the allies’ defense of South Korea.
Military experts expect the transition to change leadership and staff assignments rather than produce a wholesale redesign. Kim Jung-sup, director of the Sejong Institute, said the existing bilateral agreement makes a major restructuring unlikely. More Korean generals could instead take charge of important staff functions such as intelligence and operations, giving South Korean officers a more prominent role in planning and decision-making.
The central unresolved issue is how authority over U.S. troops assigned to combined operations would work under a Korean commander. Retired Gen. Ahn Gwang-chan questioned whether the current model could operate in the same manner if U.S. forces did not fall under the Korean commander’s operational control and instead required a separate coordination mechanism.
Other experts emphasized that the practical weight of the position will depend on whether the commander holds effective decision-making authority. The bilateral agreements governing the command also do not necessarily mean that every U.S. military unit stationed in South Korea would automatically come under Combined Forces Command control.
The debate underscores that the transfer involves more than swapping the nationalities of the commander and deputy. The final arrangement must preserve a unified wartime chain of command while clearly defining control over U.S. forces and assigning sensitive staff responsibilities. Those details will determine how much operational authority South Korea gains and how the alliance adapts its command system without weakening readiness.
