In the early morning hours of 25 June 1950, mechanized and ground units of the North Korean Peoples' Army (NKPA) rolled across the 38th Parallel into the neighboring Republic of Korea (ROK). Within 48 hours, President Harry S. Truman placed U.S. forces in Japan on alert. Within a week's time, elements of the U.S. Eighth Army, then on occupation duty in Japan, were rushed to South Korea to stem the North Korean invasion. As army soldiers, and later Marines of Brigadier General Edward A. Craig's 1st Provisional Marine Brigade, fought the NKPA to the outskirts of the port of Pusan, the United Nations undertook a series of votes that not only condemned the North Korean invasion, but brought thousands of allied troops to the assistance of the beleaguered ROK. Among the troops assigned to the Korean theater was a hastily assembled unit of Royal Marines stationed in Great Britain and Malaya, where they were already engaged in a guerrilla war against Communist terrorists.

While there was some disagreement with this decision among the Chief of the Imperial General Staff, Field Marshal Viscount William Slim, and Chief of the Air Staff, Marshal Arthur W. Tedder, both of whom argued that "Britain was already engaged in active operations in Malaya as important... in countering communist expansion as in Korea," Admiral Lord Fraser of North Cape, the First Sea Lord, strenuously advocated for the dispatch of a brigade-sized force of Royal Marines to operate in unison with the U.S. Navy as a commando raiding force. Within two weeks of Lord Fraser's decision, on 16 August 1950, a 300-man Royal Marine unit was formed and took the name 41 Independent Commando. "Independent" in the unit designation meant the commanding officer had sole responsibility for the unit and did not have to consult higher
