A military exercise, training exercise, maneuver (manoeuvre), or war game is the employment of military resources in training for military operations. Military exercises are conducted to explore the effects of warfare or test tactics and strategies without actual combat. They also ensure the combat readiness of garrisoned or deployable forces prior to deployment from a home base.
