In paintball, Freight Training is an illegal move.  Freight Training is an attempt by a tagged player to affect the outcome of a game by lingering in the game.  After being hit, the player is supposed to put their barrel plug into the end of their paintball gun and immediately exit to the nearest dead box that will not cause any interference in the game.

Ok, so we all know that paintball fields have restrictions on certain paints.  Why are these paints restricted?  There are multiple reasons.  The most common and a major reason that paint is on the banned list of your field is the paint is probably oil based.  As paintball has progressed, we have experimented and found out water based paint is much better to shoot off.  Not only do oil based paints destroy/stain the fields property, they do the same to players' gear and skin.
