A group of soldiers are split into 2 teams a ball is then added, and each team has to get the ball to the other end of the playing area. There are no rules, hence the name as it's bloody murder to play. This game is probably not allowed now for Health and Safety reasons.
The teams can be of any size, you know if you've p*ssed off the NCO's if you end up in the smaller team.
The playing area (I use the term 'playing' loosely) can be of any size.
There is no half time, the game ends when the NCO's tire of this blood sport, the bar opens or there is no one left standing.
