Green beret
The 10th Special Forces Group (Airborne) had many OSS World War II veterans in their ranks when it was formed in 1952. They began to unofficially wear a berets of varying colour while training. The color green became favored because it was reminiscent of the World War II British Commando-type beret. The 10th Special Forces Group (Airborne) deployed to Bad Tolz, Germany in September 1953. The remaining cadre at Fort Bragg formed the 77th Special Forces Group. Members of the 77th SFG began searching through their collections of berets and settled on the Rifle Green colour of the British Rifle Regiments (as opposed to the Lovat Green of the Commandos) from Captain Mike de la Pena's collection. Captain Frank Dallas had the new beret designed and produced in small numbers for the members of the Special Forces.
Commandos Marine
Commando training is the gateway to the Special Operations Forces for the Naval Riflemen. Conducted at the Fusilier Marins school at Lorient on the Atlantic coast, it provides upon successful completion entry to the commandos and the right to wear the green beret. Lasting 20 weeks, it includes one week of commando testing, six weeks of screening and preparatory training, four weeks of evaluation, the actual SOF course for seven weeks, and two weeks of parachute training. During this period, any mistake can instantly disqualify the candidate. The ultimate goal of this training is to detect individuals with the physical, intellectual and psychological potential needed to serve in the Commandos Marine. The historical roots of commando training date back to the Second World War, when Fusilier-Marins volunteers from the Free French Navy went to the Commando training center in Achnacarry, Scotland. Since then, the Commandos Marine have kept by tradition the green beret pulled right with the bronze shield badge on the left, the only such exception in the French armed forces. They have retained the principle of exceptional training without compromise, based on immersion in a highly stressful environment, close to the conditions of combat operations.
