Here comes a group of men in military uniform. They are carrying guns. They are pointing the guns at other members in the group. There is so much running around and hiding behind trees and bushes. Is there a military attack going on? No, you can relax. It is just a game of paintball.

Paintball is a game of players competing in teams or individually. The goal is to eliminate opponents by hitting them with capsules containing paint from a special gun called a tactical paintball marker. Some paintball games are organized such that the set-up follows a story. Called scenario paintball, these events many include historical re-enactments, futuristic or video game simulations. Scenario paintball events are participated in by many competitors and could last for hours and even days.
