When a citizen soldier completes his training, he takes home his individual equipment, which includes a personal weapon with a basic load of ammunition. This draft system allows the Swiss Army to maintain a potential force of 400,000 with only 2,000 full-time commissioned and noncommissioned officers. The Swiss Army is organized into three field army corps and a mountain army corps. In these four corps are six field divisions, three mountain divisions, five armor brigades, and three fortress brigades. Swiss Army forces are divided into combat troops, combat support troops, and logistics troops.
Combat troops comprise infantry and mechanized units.
Combat support troops include artillery, fortress, engineer, and signal personnel. Logistics troops include transportation, medical, maintenance, supply, veterinarian, and rescue troops. The rescue troops are unique to the Swiss Army. They provide disaster relief and are trained to use explosives for rescue purposes. They offer several classes during the year to fire departments and other agencies around the world.
