Law Firm YK announced on October 8 that it has hired Sim Woo-chan, a partner attorney with extensive experience in the defense and defense industry sectors, to strengthen its expertise and response capabilities. Sim, who previously worked at the Ministry of National Defense, the Joint Investigation Team for Defense Industry Corruption, and the presidential office, will lead YK's Defense Industry Group and expand its specialized legal services in this area.

A graduate of the 52nd class of the Army Academy, Sim has accumulated practical experience in military law, defense administration, and investigations related to defense projects. After passing the bar exam in 2008 and completing his legal training, he served in various roles, including as a legal officer for the Army's 1st Corps and as a prosecutor assigned to the Joint Investigation Team for Defense Industry Corruption in 2014.

Following his time at the presidential office, where he worked as an administrative officer in the Office of Legal Affairs, Sim joined the compliance department of SP Nature, a subsidiary of Sampyo Industries, in 2022. He also became a member of Kakao's Responsible Management Committee in 2024, where he provided legal advice and risk management related to the company's internal control and audit systems.

Sim is known as the son of former South Chungcheong Governor Shim Dae-pyeong and the brother of former Prosecutor General Shim Woo-jung.

With Sim's addition, YK plans to enhance the existing expertise and collaborative framework of its Defense Industry Group. This group includes attorneys and experts with experience in legal, investigative, and command roles across the Army, Navy, Air Force, and Marine Corps.

The group features partner attorney Bae Yeon-gwan, a former naval prosecutor, along with Kim Min-hyuk, a former military legal officer, Hong Seok-il, who served as a legal officer at the Army Training Center, and Lim Ho-kyun, a former Air Force legal officer. Additionally, the group includes over ten experts, such as former Marine Corps Commander Jeon Jin-gu and Gu Tae-bon, who has extensive experience in military investigations from the Ministry of National Defense and the Ground Operations Command.

The defense and defense industry sector encompasses a range of legal issues, including military criminal and disciplinary cases, investigations related to defense projects, administrative sanctions, various contracts and regulations, and corporate internal controls and compliance. YK aims to enhance its response capabilities in the defense and defense industry sectors by combining Sim's experience in defense project investigations and legal compliance with the existing members' military judicial, investigative, and command experience.

Sim stated, "The defense and defense industry sector requires a comprehensive understanding of military organizations and defense projects, as well as the relevant laws, policies, and various issues and risks surrounding companies. Based on my experiences in the military, government, and corporate sectors, I will closely collaborate with the experts in YK's Defense Industry Group to provide clients with practical solutions."
