Ammunition control
Prior to 2007 members of the Swiss Militia were supplied with 50 rounds of ammunition for their military weapon in a sealed ammo box that was regularly audited by the government. This was so that, in the case of an emergency, the militia could respond quickly. However, since 2007 this practice has been discontinued. Only 2,000 specialist militia members (who protect airports and other sites of particular sensitivity) are permitted to keep their military-issued ammunition at home. The rest of the militia get their ammunition from their military armory in the event of an emergency.[13]
To carry a loaded firearm in public or outdoors (and for an individual who is a member of the militia carrying a firearm other than his Army-issue personal weapons off-duty), a person must have a Waffentragbewilligung (gun carrying permit), which in most cases is issued only to private citizens working in occupations such as security.[14] It is, however, quite common to see a person serving military service to be en route with his rifle, albeit unloaded.[15]
Conditions for getting a Carrying Permit
There are three conditions:
fulfilling the conditions for buying a permit (see section above)
stating plausibly the need to carry firearms to protect oneself, other people, or real property from a specified danger
passing an examination proving both weapon handling skills and knowledge regarding lawful use of the weapon
The carrying permit remains valid for a term of five years (unless otherwise surrendered or revoked), and applies only to the type of firearm for which the permit was issued. Additional constraints may be invoked to modify any specific permit. Neither hunters nor game wardens require a carrying permit.
