The term 'Special Forces Hat' refers to the BERET, a type of headgear that is traditionally worn by military personnel. The BERET is a soft, round, flat-crowned hat that is usually made of wool and is typically worn with the brim pulled down over the forehead. It has been adopted by many Special Forces units around the world as part of their uniform. The BERET is often associated with the French military, but it has also been adopted by other countries, including the United States.
