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.

After the creation of the special operations unit in 1981, the CTOE ceased to be just an instruction facility but also served as the HQ for the new Portuguese special operations unit. The unit members wear a grass green beret and are the heir of the Special Hunters: the beret badge includes a trumpet — a symbol of the Special Hunters; and the unit is known as Rangers because the first instructors of the Special Hunters completed the Ranger Course and adapted the characteristics of that training to the Special Operations Course. The unit has operated in Bosnia and Herzegovina, East-Timor, Kosovo, Afghanistan, and Iraq.The CTOE has several courses:For those already badged as special operations soldiers, there are also courses outside the CTOE:Special Operations soldiers also take courses in friendly countries:
