Well, back in my days in SAC, we used to say of ourselves. "We're SAC trained killers; we can take any sack, two out of three falls."
Then there was, for the ICBM folks, "SAC. When it absolutely, positively has to be there in 30 minutes or less!"
Up at Malmstrom AFB (a SAC base), I'm told (never stationed there, but a friend was) there was a sign that read, "This is not the end of the world...but you can sure as hell see it from here!"

That's a good one. Tech school for the missile maintenance guys used to be at Chanute AFB, IL. I remember we used to say, "Shoot me, but please don't Chanute me!"
