There are not many pieces of equipment involved in an American wheelchair football game.  The only necessary items are a field, wheelchairs, and a ball.  As mentioned, the field should include boundary and goal line markers, as well as a goal post/target for field goals.  Any type of chair can be used, from a standard daily use chair to a sports chair to a motorized chair.  Finally, the type of ball can vary greatly, from a softer, Nerf-type ball to a more traditional leather ball of any size.  Additionally, if an individual with vision impairment or blindness is playing, a noise-emitting ball may be used to help them know where it is throughout the game.
