President Lee Jae-myung visited a front-line Marine Corps unit at Yeonpyeong on Wednesday to demonstrate military readiness and outline future defense reforms [1].

The visit signals a potential shift in South Korea's national security strategy as the administration weighs the transition from mandatory conscription to a professionalized force. This balance of maintaining a strong deterrent against North Korea while modernizing personnel structures is critical for long-term regional stability.

During the visit to the West Sea base, President Lee rode in a K9 self-propelled howitzer to inspect equipment and boost troop morale [1]. He also participated in a live-fire exercise using a K2 rifle, where he fired 10 rounds and hit the target with every shot [1].

President Lee said the necessity of a strong deterrent force is required to ensure national security [2]. While stressing readiness, he announced plans to reduce the current requirements for conscription and said he is considering the implementation of a volunteer-military system [2].

These announcements come ahead of the 76th anniversary of the Korean War [2]. The president is scheduled to attend the anniversary ceremony on Thursday to mark the historical conflict and reaffirm the nation's commitment to defense [2].

The administration's focus on a volunteer system aims to address the evolving needs of the military in a changing demographic landscape. By combining high-tech weaponry, such as the K9 howitzer, with a more professionalized soldier corps, the government seeks to maintain a qualitative edge over adversaries [1], [2].

President Lee announced plans to reduce conscription and consider a volunteer-military system.

The proposal to shift toward a volunteer-military system reflects South Korea's struggle with a shrinking youth population, which makes maintaining a massive conscript army increasingly difficult. By emphasizing 'strong deterrence' through high-tech assets like the K9 howitzer while reducing mandatory service, the Lee administration is attempting to modernize the force without appearing to weaken the nation's defensive posture against North Korea.
