@Sandwich,
Having been at both situations, (Being an AA gunnery sargeant), anti-terrorism and anti-infiltration tactics were fun, working with/without dogs to capture infiltrators was loads of fun. Also, the first day chew out...running with hands behind your head instructors yelling at you to report your name all the time...
midnight drills. "Time-to-gun". "Pearl harbor" excercises...
1800 hours of guarding duty... waiting for the dawn and thinking you need to fry your feet to get them walking again..
Maintaining 50+ anti aircraft guns 20mm and 30mm caliber. NOT FUN AT ALL!!
Actually I remember 2 things of that period. One was the "off the record" training as to how to down a hijacked hiliner.
Second was the Senior Non-com instructing us Sarges that should the need arise we SHOULD kill any of our gun crew that faced with fear, ran. I swore then I wouldn't.
--> Then there was the camaderie, and the hatered for those who "didn't carry a gun"
When I had 5 months left I was assigned to an office for database maintaining (basically scrap the old and start anew... 30000 cells worth of it...) I just couldn't believe the things some of the other "clerks" did to avoid ANYTHING. Seemed that their only care in life was finding someone to dump their work TO! I mean, to pretend that someone's mother was terminally ill to avoid guarding duty (Ye gods!)
Of course, by night I was back with my unit, either guarding or 5-min readiness (my fave duty), where we would gather in front of the tv, cook food, wait for the night to end (and let some of those that couldn't) sleep. Of course, if some "tech" managed to come over (except if invited by one of us), he would get "washed".

Yet, when I had a problem (My sister got her degree and I had to "skip town" for a few hours), my buds backed me up. Had I been a tech, they would pile on my corpse demanding jail time for me like flies on ****.
You were a tanker huh? The only thing I can say is that maintaining an Artemis 30 is like having a tank without the engine.
@Fry,
Take care and NEVER betray your own.
