[Airborne Butters]

For your clothing, don't worry too much about it. Honestly, you're going to feel the sting when you get hit. It doesn't hurt as much as they say, but you'll feel it. Wear pants and long sleeve shirt. Regular pair of shoes should work too. If you have cleats, all the better, especially if you're playing on a paintball field and it's soaked with paint and shells.

As far as your strategy is going to go, it's nothing like a war movie or any of that bs. Best bet is to stretch out before hand, because you're going to be moving around alot and crouching. You can outflank people and such, but most of the fighting is going to be you and other people just kind of spraying at each other trying to get in the hit. Also, don't be afraid to rush people and try to bunker them. Just remember to keep moving and not stay in one spot / cover for too long.
