Military service in Switzerland is compulsory and all male Swiss citizens
incorporated in combatant militia units are taught how to shoot, beginning
at age 20 with basic military training. Rifle clubs teach younger men how to
shoot in voluntary preparatory courses.
All combatant militia troops (ages 20 to 50) are obliged to keep their
personal weapon, normally an automatic assault rifle and ammunition at home.
It is strictly forbidden to use the military weapons for any non-authorized
purposes. While each militiaman keeps some sealed ammunition at home, he is
under no circumstances allowed to use the ammunition for any private use.
A militiaman who uses his military weapon for unauthorized and improper
purposes may, under military criminal law, be sentenced to prison or, if the
offense is of small gravity, be punished by disciplinary action.
