I imagine that for a lot of people who'd be successful at it they might prefer not to fall back on things from their old life when they're trying to assimilate into a civilian life. Not everyone, obviously. But enough that it's not widely prevalent. 

On a side note, the movies that take that route always seem to involve explosions.

Funny enough, I can't actually think of any movie where that's the plot, haha. Like, there's sveral lone former soldier guys who becomes vigilantes. (Shooter, Die Hard, John Doe, etc, etc.)

But none where it's a big ol squad of 10+ people. The Losers is probably as close as I can think off.
