The mission of the Field Artillery is to destroy, defeat, or disrupt the enemy with integrated fires to enable maneuver commanders to dominate in unified land operations. The Field Artillery is one of the Army's combat arms, traditionally one of the three major branches (with Infantry and Armor). It refers to those units that use artillery weapons systems to deliver surface-to-surface long range indirect fire. Indirect fire means that the projectile does not follow the line of sight to the target.
