The battle was followed by a rapid collapse of the KPA within a month of the Incheon landing, the Americans had taken 135,000 KPA troops prisoner.

MacArthur was the driving force behind the operation, overcoming the strong misgivings of more cautious generals to a risky assault over extremely unfavorable terrain. The UN and ROK forces were commanded by General of the Army Douglas MacArthur of the United States Army. The subsequent UN recapture of Seoul partially severed the KPA's supply lines in South Korea. The battle ended a string of victories by the North Korean Korean People's Army (KPA). Through a surprise amphibious assault far from the Pusan Perimeter that UN and Republic of Korea Army (ROK) forces were desperately defending, the largely undefended city of Incheon was secured after being bombed by UN forces. The battle began on 15 September 1950 and ended on 19 September. The code name for the operation was Operation Chromite. The operation involved some 75,000 troops and 261 naval vessels and led to the recapture of the South Korean capital of Seoul two weeks later. Tank crews had to watch as carefully as infantry for land mines.The Battle of Inchon ( Korean: 인천상륙작전 Hanja: 仁川上陸作戰 RR: Incheon Sangnyuk Jakjeon), also spelled Battle of Incheon, was an amphibious invasion and a battle of the Korean War that resulted in a decisive victory and strategic reversal in favor of the United Nations Command (UN). It was in this role that American Sherman crews came into contact with Australian troops, as they did in the battle of Kapyong, April 1951.

After several large tank battles in July and August 1950, the American armoured units' most common task was the support of infantry operations.

Armed with a 76 mm gun, the Sherman was outclassed by North Korea's T-34/85 tanks. It was powered by a Ford eight-cylinder petrol engine and could attain a top speed (on road) of 48 kilometres per hour. The M4A3E8 version of the Sherman had a crew of five. The most widely used Allied tank in the Second World War, the Sherman tank, again saw service with American armoured units in Korea.
