Swiss men spend only a total of about ONE year in their 30 year military life.
Today, military service for Swiss males is universal. At about age 20, every Swiss male goes through 118 consecutive days of recruit training in the Rekrutenschule. This training may be a young man's first encounter with his countrymen who speak different languages. (Switzerland has four official languages: German, French, Italian and Romansch.)
Even before required training begins, young men and women may take optional courses with the Swiss army's M57 assault rifle. They keep that gun at home for three months and receive six half-day training sessions.
From age 21 to 32, a Swiss man serves as a "frontline" troop in the Auszug, and devotes three weeks a year (in eight of the 12 years) to continued training. From age 33 to 42, he serves in the Landwehr (like America's National Guard); every few years, he reports for two-week training periods. Finally, from ages 43, to 50, he serves in the Landsturm; in this period, he only spends 13 days total in "home guard courses."
Over a soldier's career he also spends scattered days on mandatory equipment inspections and required target practice. Thus, in a 30-year mandatory military career, a Swiss man only spends about one year in direct military service. Following discharge from the regular army, men serve on reserve status until age 50 (55 for officers).
