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".
