The "Cap"

*Smacks Head* “ I'm not trying to be intentionally crude here, but ... Literally millions of American servicemen have served their country wearing what was/is  universally called the "Cunt Cap."  I don't even remember what the proper nomenclature is, but a common directive from the Master Sgt. was "Fall-in in 20 minutes.  Dress will be khaki and  cunt cap."  I never actually understood why it was called that— until just now.  I'm guessing that GIs coming home from deployment in some European country, who had contact with our Russian allies,  started it even though the two are not at all technically similar.  Ours should have been called something like "soda jerk" cap. ”
