The point of military service isn't to fight wars abroad, which americans seem to do a lot, but to train reservists who can later defend the country if needed. It ranges between 6-11 months I think, which wouldn't give you enough time to both train the people and get something done anyway.
Civilian service or whatever is the correct term is in english, isn't soldiers doing civilian stuff, but an alternative path for those who don't want to be in the military. You'd work for some public organization, as a civilian.
