All Arms Commando Course
The All Arms Commando Course (AACC) lasts for 8 weeks and is run by the Royal Marines at the Commando Training Centre Royal Marines (CTCRM), Lympstone. Members from any of the United Kingdom's Regular Armed Forces (e.g. personnel from units attached to the Marines) and overseas exchange personnel can attend to serve with 3 Commando Brigade (3 Cdo Bde RM). On completion of the course the successful candidate earns the right to wear the green beret, and to wear the "Commando Dagger" on their uniform. The Royal Marines expects that nearly half of the volunteers will drop out or be dismissed before completing the AACC.
The course is open to both men and women. In 2002 Major Philippa Tattersall of the Adjutant General's Corps became the first woman to have successfully completed it.
Background
The first formal commando training course was established at Achnacarry in 1942 and some elements remain exactly the same to this day, such as the "rope regain" and the "Tarzan course", designed to test the courage, agility and determination of candidates. Others have changed in times and distances, such as speed-marching and the endurance course. The specific tests which volunteers are put through are not as important as the fact that their fortitude should be tested to the limit. The basis of the commando ethos can be summed as unity (unselfishness), adaptability, humility (as in non-arrogant), high professional standards, fortitude and humour (cheerfulness in the face of adversity).
