C-9: Defensive Echelonment

Previous: C-8: Echelonment of Indirect Fire

C-9. In defensive missions, echeloning fires are scheduled based on their optimum ranges to maintain continuous fires on the enemy, disrupting his formation and maneuver. Echelonment of fires in the defense places the enemy under increasing volumes of fire as he approaches a defensive position. Aircraft and long-range indirect fire rockets and artillery deliver deep supporting fires. Close supporting fires such as final protective fires are integrated closely with direct fire weapons such as Infantry weapons, tank support, and antiarmor weapons systems. Figure C-1 illustrates an example of defensive echelonment.
