when Jerry Pournelle wrote about System D
"System D is a Line troop tradition. The men organize themselves into small units and go into a section of town where they all drink until they can't hold any more. Then they tell the saloon owners they can't pay. If any of them causes trouble, they wreck his place, with the others converging onto the troublesome bar while more units delay the guard."
