Green beret
When visiting the Special Forces at Fort Bragg on 12 October 1961, President John F. Kennedy asked Brigadier General William P. Yarborough to make sure that the men under his command wore green berets for the visit. Later that day, Kennedy sent a memorandum which included the line: "I am sure that the green beret will be a mark of distinction in the trying times ahead". By America's entry into the Vietnam War, the green beret had become a symbol of excellence throughout the US Army. On April 11, 1962 in a White House memorandum to the United States Army, President Kennedy reiterated his view: "The green beret is a symbol of excellence, a badge of courage, a mark of distinction in the fight for freedom". To no avail, both Yarborough and Edson Raff had previously petitioned the Pentagon to allow wearing of the green beret. The President, however, did not fail them.
Special Operations Troops Centre
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:
