Yeah, low level input operator.
Like when they really killed of a few hundred troops at JRTC.
In one of the early rotations when JRTC was just getting started somebody in the Brigade S-1 shop forgot to clear all the play casualties. Went back to home station, plugged in an "poof" they were dead. IIRC nobody really noticed until payday - then the SHTF.
Took a while to undue since when the Army says you're dead - you are dead.
