Universal Trench (often referred to as Universal Trap, Five Trap or UT) is an international shooting discipline governed by FITASC.
Each round of Universal Trench consists of 25 single targets with two shots allowed at each one. Scoring is based on a single point being awarded for each hit, regardless of whether it was the first or second shot. Most domestic competitions are shot over four rounds making a total score out of 100. Selection shoots for the GB Team and most international competitions are shot over 200 targets.
When a shooter calls for a target it will be released immediately from one of a group of five traps (see below). The shooters do not know which trap will be triggered, and therefore which target they will receive, which gives the feeling of a random selection of targets. In reality however, each Universal Trench layout is based on a 'scheme' which is controlled by a computer. This means that, although the sequence of the targets will be different for each competitor, they will all receive the same targets by the end of the round.
Universal Trench is shot in squads of six over five stands using a 'shoot and move' method where the shooter moves to the next stand to their right after taking each shot (stand five moves round to wait behind stand one).
Universal Trench requires five traps set approximately 1m apart in a trench 15m in front of the shooters.
Each trap is set to send targets 60m-75m at various elevations (1.5m-3.5m high at 10m from the trap) and various horizontal angles (0 to 45°).
Universal Trench must be shot with cartridges that have a maximum load of 28g and shot size no greater than 2.5mm.
