You know the basics that are needed for playing paintball. You need a marker of course, goggles, gloves, a jersey for body protection and layers of clothing under that doesn't hurt either. You also need boots and a good paintball mask. After you have the basic equipment down you will want to move on to other items that make your game a whole lot more fun.

Ready, Steady, Don't Move
Land mines are a blast -literally to have in your paintball game. They work by being placed on the ground with just a dusting of dirt or leaves across them. Don't put them deeply into the ground of the mine won't react to the weight of someone stepping on it by sending a blast of paint at the stepper. If you're playing a capture the flag type of game, put a mine outside the immediate perimeter of your flag. Your opponent will be expecting mines closer to the flag - you can take out a number of opponents with this technique. If you use audio communications equipment, develop a one word term for a land mine that is imminent in case one of your own players is about to experience friendly fire from forgetting one of your own mines is placed.

Paint Out!
Grenades are another fun piece of equipment that can make a bunker game even more interesting. When you throw a grenade, yell "Paint out" to your team members that are in the vicinity which is a take off on the actual term when a real grenade is thrown the term is "Frag out". If a grenade lands near you, yell "Grenade" and move or you'll most likely experience a good deal of paint coverage.
