Guy on the right has some kind of paintball gun it looks like. I wonder what kind of nasty chemical is in those paintballs?

Those guys all combat-vogueing must be thinking they're like the Marines at Iwo Jima. Far, far from it.

It’s a modified paintball gun filled with pepper balls.

Exact one is here.
