Korean War: The Chinese People's Volunteer Army begin assaulting positions defended by the Royal Australian Regiment and the Princess Patricia's Canadian Light Infantry at the Battle of Kapyong.

The Korean War was an armed conflict on the Korean Peninsula fought between North Korea and South Korea and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations Command (UNC) led by the United States. The conflict was one of the first major proxy wars of the Cold War. Fighting ended in 1953 with an armistice but no peace treaty, leading to the ongoing Korean conflict.

The People's Volunteer Army (PVA), officially the Chinese People's Volunteers (CPV), was the armed expeditionary forces deployed by the People's Republic of China during the Korean War. Although all units in the PVA were actually transferred from the People's Liberation Army (PLA) under the orders of Chairman Mao Zedong, the PVA was separately constituted in order to prevent an official war with the United States. The PVA entered Korea on 19 October 1950 and completely withdrew by October 1958. The nominal commander and political commissar of the PVA was Peng Dehuai before the ceasefire agreement in 1953, although both Chen Geng and Deng Hua served as the acting commander and commissar after April 1952 following Peng's illness. The initial units in the PVA included 38th, 39th, 40th, 42nd, 50th, 66th Corps; totalling 250,000 men. About 3 million Chinese civilian and military personnel had served in Korea throughout the war.

The Royal Australian Regiment (RAR) is the parent administrative regiment for regular infantry battalions of the Australian Army and is the senior infantry regiment of the Royal Australian Infantry Corps. It was originally formed in 1948 as a three battalion regiment; however, since then its size has fluctuated as battalions have been raised, amalgamated or disbanded in accordance with the Australian government's strategic requirements. Currently, the regiment consists of seven battalions and has fulfilled various roles including those of light, parachute, motorised and mechanised infantry. Throughout its existence, units of the Royal Australian Regiment have deployed on operations in Japan, Korea, Malaya, Borneo, Vietnam, Somalia, Rwanda, Cambodia, East Timor, the Solomon Islands, Iraq and Afghanistan.
