Every able bodied male in Switzerland spends time as part of the Swiss Armed Forces. About one third of the total male population is excluded for various reasons from the armed services, and these either serve in Civil Protection or Civilian Service to meet their obligation.
You can pull a straight 300 day conscription, or be part of the reserve forces and train three weeks every year until age 30.
On May 18, 2003, Swiss voters approved the military reform project "Army XXI" to drastically reduce the size of the Swiss Army. Starting in January 2004, the 524,000-strong militia was pared down to 220,000 conscripts, including 80,000 reservists. They have 1,579,921 (yr 2000 est) military age and fit for duty males available for activation if need be.
The swiss keep their rifle (usually a Sturmgewehr 90 or F bellybutton 90) and uniform at their residence with 50 accountable rounds in a sealed tin.
They can mobilize a very large number of trained soldiers in a very short period of time if they saw a need.
