The army chooses to train its soldiers in the Brecon Beacons because it offers "tough and demanding" training to prepare soldiers for the front line.
- Infantry Battle School is based in Brecon and it prepares soldiers for "high-intensity, light-role war fighting" according to the Army.
- Soldiers are trained in a number of skills including command and leadership, weapons, live fire qualification and different tactics used by the infantry.
Emotional tributes have been paid to a third army reserve soldier who died from injuries sustained during SAS selection training.
One of two Army reservists killed in a military exercise in the Brecon Beacons on Saturday has been named as Lance Corporal Craig Roberts.
