The Swiss army has long been a militia trained and structured to rapidly respond against foreign aggression. Swiss males grow up expecting to undergo basic military training, usually at age 20 in the Rekrutenschule (German for "recruit school"), the initial boot camp, after which Swiss men remain part of the "militia" in reserve capacity until age 30 (age 34 for officers). Each such individual is allowed to keep his army-issued personal weapon (the 5.56x45mm Sig 550 rifle for enlisted personnel or the SIG 510 rifle and/or the 9mm SIG-Sauer P220 semi-automatic pistol for officers, medical and postal personnel) at home with a specified personal retention quantity of government-issued personal ammunition (50 rounds 5.56 mm / 48 rounds 9mm), which is sealed and inspected regularly to ensure that no unauthorized use takes place.
