There were quite a few in the early 70s.
We had a Catholic Chaplain that was a real fire pisser. Airborne-Ranger type that carried his own M-16 every chance he had in the field. The guy actually took a straight razor awway from a pimp and beat the hell out of him for not keeping his stable cleaned up.
Then we had a 1SG that was a TINY little guy that feared nothing. One time he actually put a milk crate down in front of a tall recaltricent soldier, stood up on it and slapped the shit out of him.
Another 1Sg coulden't read very well, so he'd memorize the battery roster. When he got to the end, he'd say 'Sum Total' and somebody would yell "Here!" Story was, if nobody answered, he'd run around looking for Private Sum Total all day.(It was bullshit.)
One day old Top came out to formation and said: "Last night one a you guys shit in the corner of the motor pool, and I'm gonna find out who did it. Now some a you guys are gonna try tell me some dog did it, but you can't fool Old Top because I ain't never heard of no dog usin' no toilet paper!"
God, we had some real characters back then.
