Some of the European countries phased their mandatory conscription programs out as recently as the 90's-00's, and it's maybe not the ones you might first assume who had them in the first place - the Danes, Swedes, Finns, the Swiss, etc. Others still have conscription in case of war, but that's not so unusual at all, and may not mean front-line posts for many who're unfit for the duty for one reason or the other.

Many roles in a nation's military are far from the front, everything from administrative, intelligence analysis, supplies and warehousing, medical roles - there's a pretty wide spread of tasks beyond holding a gun and firing it at your nation's enemies.
