Demaiter: you reminded me of a time I was playing paintball and I actually did point shoot. In paint ball there is a rule that if you catch someone real close (e.g. walk up behind them) you have to say surrender or die and if the captured player does not surrender then you can shoot. I was walking along a trail and I heard, "Surrender or die" so I instinctively turned towards whereI heard the noise and pulled the trigger. Turns out I had a bulls-eye at about 10-15 feet. The guy had hidden inside a cedar tree so you couldn't see him!
I guess you could say I used the underarm assault position according to the essay Mr. Temkin wrote.
