I have always thought of the beret as a symbol of elitism. Wearing a beret sets you apart from everyone else and the fact that most people in the USAF who wear a beret only get it after they complete all of their training and tech schools means they had to work that much harder to earn the right to wear it.
Beret's dont have to be the most combat practical head gear out there because you dont wear it in combat.
The British Armed Forces have been issued berets as standard for decades. The colour differs as to which section of the Forces you're in. The Marines wear a green beret, the paras wear red berets, the RAF wear blue berets. I never really thought the American forces would wear berets, perhaps I've seen too many Second World War films where all the Americans wear those triangular hats, it's probably dug in to my self-conscience now.
Triangular hats???? Sure you arent talking about George Washingtons Army? :lol: I have no idea what hat you are speaking of.
This whole subject of Berets, hats....I always found that a well oiled US Army Ranger Patrol Cap felt great, had some practical use. Boonie was next....Berets were for show though I liked them. K-Pot....now THERE is one comfortable mofo. :lol:
