40 Commando RM is a battalion-sized formation of the British Royal Marines and subordinate unit within 3 Commando Brigade, the principal Commando formation, under the Operational Command of Commander in Chief Fleet. Their barracks are at Norton Manor Camp, Norton Fitzwarren near Taunton in Somerset. Tasked as a Commando light infantry unit, 40 Commando (pronounced "Forty Commando") is capable of a wide range of operational tasks. Personnel regularly deploy outside the United Kingdom on operations or training. Whilst 3 Commando Brigade RM are the principal cold weather warfare formation, personnel are capable of operating in a variety of theatres including tropical jungle, desert or mountainous terrain. The Commando is a regular participant in the annual Brigade cold weather warfare exercise in Norway. The unit's first "winter" was 1991, until which the unit was nicknamed the "Sunshine Commando". All personnel will have completed the Commando course at the Commando Training Centre (CTCRM) at Lympstone in Devon, entitling them to wear the green beret, with attached personnel having completed the All Arms Commando Course.

The first Royal Marines commando unit was formed at Deal in Kent on 14 February 1942 and designated 'The Royal Marine Commando'. Before long it was re-designated RM 'A' Commando. Col J Picton Phillips was the Commanding Officer. Dieppe Raid The Commando's first assignment was at Dieppe on 19 August 1942. In support of the main Canadian assault force, Nos. 3 and 4 (Army) Commandos were to destroy the enemy coastal batteries covering the main landing beaches, whilst No. 40 had selected tasks in the port area and was to be responsible for reinforcements as required. In the pre-dawn run-in the landing craft of No. 3 were fired upon and scattered with the result that only two small parties managed to land, one was overwhelmed, but the other successfully engaged the Berneval battery for some hours before withdrawing. On the other flank at Varengeville No. 4, under the command of Lord Lovat, carried out what was officially hailed as a 'classic operation of war' and completely destroyed the Hess Battery, successfully withdrawing and re-embarking with prisoners. Unfortunately, No. 40, when committed to their landing, under well-nigh impossible conditions, suffered severe casualties. Of the 370 officers and men,
