Did soldiers serve the length of the war or just as their tours of duty?

Soldiers typically served for the length of their tours of duty rather than the entire duration of a war. A tour of duty is a specified period during which a soldier is deployed to a combat zone, often lasting several months to a year. After completing their tour, soldiers could return home, though some chose to re-enlist or extend their service. This rotation system helps manage troop levels and provides relief for soldiers and their families.
