Commonwealth Division (Korea) Shoulder badge, 1951-52 The 1st Commonwealth Division was the name given, after July 1951, to Commonwealth land forces in the Korean War. The division was a multinational unit that was part of British Commonwealth Forces Korea, and whilst British and Canadian Army units formed the bulk of the division, Australian infantry, New Zealand artillery and an Indian medical unit were also a part of the division. As with the US "KATUSA" programme, numerous South Korean troops were seconded to the Commonwealth division to make up numbers under a programme known as "KATCOM". The Division was made up of 58% British forces, 22% Canadian forces, 14% Australian forces, 5% New Zealander forces, and 1% Indian forces. The 1st Commonwealth Division was part of the US I Corps, which also included the US 1st Cavalry Division, the US 3rd and 25th Infantry Divisions, and the ROK 1st Division. The division occupied the strategically important sector of front on the Jamestown Line, stretching from the Kimpo Peninsula on the Yellow Sea coast to a point east of Kumhwa about 10.1 km, and just 48 km from Seoul. It was deactivated in 1954 as part of the demobilisation of forces in Korea in the aftermath of the war.
