Firearms training is serious stuff. You remember "we do dangerous things". However, just because it is serious doesn't mean it can't be fun and innovative.
In this video - released on Halloween - Rob Pincus shows a class how to counter a Zombie ambush. It could just as easily be a mob of crazed anarchists from Occupy (Insert City Name) on a rampage who have surrounded your stalled vehicle.
It looks like a fun - and challenging - exercise.
