7-88. Anticipating sustainment requirements effectively requires an understanding of the type of battle the corps and division commanders expect to fight. For example, fighting peers with air forces requires large quantities of AMD munitions. Consumption may be relatively light in attacks against weakly defended locations. Units fighting enemy infantry in restricted and urban terrain use large quantities of small arms and artillery ammunition and water. Breaching and wet-gap operations consume large amounts of obscurants. Units attacking enemy armored forces require large quantities of anti-armor munitions and fuel. Ensuring that maneuver and sustainment commanders share a common visualization of how a battle should unfold enables more responsive sustainment. Sustainers operationalize their support based on the mission variables unique to each case.
