'Shack". Is one I've heard within the tactical fighter community. It's,another way to agree with something or acknowledge something.

Heard throughout the Navy, and generally, throughout the day: "shit, man, f**k!" It expressed a wide variety of responses to situations, feelings, orders, officers, chow, etc. One could register a pleasant reaction to something-or negative. It had universal applications. Say, you're reading the POD and see you drew the 4 to 6 compartment watch: "shit, man, f**k! " Or liberty call: "shit, man, f**k!" I'm surprised we never heard it on the bitch box: "now hear this: shit, man, f**k!!"

Army, specifically Airborne.

First heard in Navy basic, but common therafter, is especially on Field Day. Usually spoken by a Chief with his everpresent coffee cup: "Awright you mutts, Turn to! I wanna see assholes and elbows!" A reference to getting everything spotless for inspection. Sometimes mutts could be changed to much more colorful, but descriptive terminology.

Golly, for the Army, when I was in back in 1948-51, I do not remember any of the words I have read here. However, there are some I remember that are not printable here. :-)
