Well, we did march in formation with briefcases to our tech school classes. I never shouldered a weapon or had chemical warfare training in six wonderful years in the USAF. Oh, I am a Vietnam Era Vet by less than two months before it closed on May 7, 1975 and was one of the last flights to be issued the 1505 khaki uniforms in basic training.
I remember 1505s. And c**t caps. And Chukka boots.
