There, fixed that for you... =J
My grandfather worked there for a while & was basically told The Rules as you've described them.
Deviation wasn't grounds for being fired, it was usually grounds for being fired UPON.
"Shoot First, Ask Questions Later" wasn't an "option", it was SOP.
*Wibble* =}

He later went on to work at AeroJet GenCorp in their R&D facilities in Rancho Cordova &, despite still being in a maximum security facility, would often joke "At least now I don't need an armed guard to go take a dump!"
(COUGH *chuckle*) =)P
