Army 2nd Infantry Division Challenge Coin. The 2nd Infantry Division is unique in that it is the only U.S. Army division that is made up partially of South Korean soldiers, called KATUSAs (Korean Augmentation to the U.S. Army). This program began in 1950 by agreement with the first South Korean president, Syngman Rhee. Some 27,000 KATUSAs served with the U.S. forces at the end of the Korean War. As of May 2006, approximately 1,100 KATUSA soldiers serve with the 2ID. There were also more than 4,748 Dutch soldiers assigned to the division between 1950 and 1954. Denoted the 2nd Infantry Division-ROK/U.S. Combined Division (2ID/RUCD), the division is augmented by rotational BCTs from other U.S. Army divisions. Brand New!
