Asked my Vietnam vet (SAC, Seoul SoKor) Brother in law, “What would you do if you heard the Call to Colors at midnight?
He replied, “I’d take my hand off my ***, jump out of bed and come to attention and hope nobody would notice.”
Funny, but he said, the whole barracks would be at attention and saluting.
