As its name indicates, this is one of the disciplines which forms part of the shooting programme at the Olympic Games. A trench in front of the shooting stands conceals 15 traps arranged in 5 groups of 3. Shooters take turns to shoot at a target each, before moving in a clockwise direction to the next stand in the line. Targets for each shooter are thrown immediately upon his call and are randomly selected from any one of the three traps directly in front of him/her. Scoring is done of the basis of 1 point per target killed, regardless of whether this is achieved with the first or second barrel.
