Combat support should not be confused with combat service support, which are units which primarily provide logistical support by providing supply, maintenance, transportation, health services, and other services required by the soldiers of combat units to continue their missions in combat. Expressed another way, Combat Support units are focused on providing operational support to combat units, while Combat Service Support units are focused on providing logistical support to combat units. Actual combat units are collectively referred to as combat arms units; hence, all army units fall into the category of either combat arms, combat support, or combat service support.^[2]
