When I was in Air Force ROTC at the U of Maryland I was razed a bit as a Junior Birdman - not helped by the fact that many of my class-mates were 5 years older than I.
And I was there when the Air Force changed from army khaki to blue uniforms. Further razing as "Greyhound bus drivers", since many commuted to school on Greyhound. I'll admit that there was some similarity.
Oops, no one could be THAT old....
