CAMP HUMPHREYS, South Korea — An American soldier raised in South Korea died Tuesday at a hospital on Camp Humphreys, the 2nd Infantry Division said in a news release.

Spc. Lee Sun-Ho, 31, originally of Guri, South Korea, was pronounced dead at the Brian D. Allgood Hospital, according to Thursday’s release. The circumstances of Lee’s death are under investigation, according to the 2nd ID.

Lee was a team leader assigned to the 23rd Chemical, Biological, Radiological and Nuclear Battalion, 2nd Infantry Division Sustainment Brigade, Republic of Korea-U.S. Combined Division.

“There are few words to express the grief the unit feels in the loss of [Lee],” battalion commander Lt. Col. Raul Salinas said in the release. He called Lee "a dedicated professional, with a soldier’s heart, who, throughout his two years in this battalion, selflessly executed his job, and went out of his way to help others across organizations here on Camp Humphreys.”

Lee “epitomized” the battalion’s motto of “two joined as one,” Salinas said. The motto refers to the division’s unique composition of soldiers from the United States and South Korea.

Lee enlisted in the Army in September 2020, according the release. Guri is directly east of Seoul and roughly 40 miles north of Humphreys, the largest overseas U.S. military base.

His awards include the Army Commendation Medal, Army Achievement Medal, National Defense Service Medal, Global War on Terror Service Medal, Korean Defense Medal, Army Service Ribbon and Overseas Service Ribbon.
