Being a visual learner, I drew a floor plan on a piece of poster board and used my son's little green fighting men to represent the action. The grenade-thrower represented "one" of the ruffians and the candidate switched between the rifleman firing from the shoulder, the kneeling bazooka-man, and the prone rifleman, as appropriate. My mentor heard about this and invited me to demonstrate the exercise to some assembled PMs. So, I rehearsed the initiation of "Mr. Rock, Sergeant, USMC"
I hammed it up. They laughed their backsides off. But, I got it all right.
