Fire Support in Depth During Large-Scale Ground Combat Operations 30 April 2020 FM 3-09 6-31 Figure 6-6. Defensive encirclement operations MOBILITY OPERATIONS 6-136. Freedom to move and maneuver within an OA is essential to the application of combat power and achieving results across the range of military operations. An OE will present numerous challenges to movement and maneuver. These are typically overcome through the integration of combined arms mobility and countermobility in support of mission requirements. BREACHING OPERATIONS 6-137. The plan must synchronize combat multipliers to isolate the point of penetration. A breach is a synchronized combined arms activity under the control of the maneuver commander conducted to allow maneuver through an obstacle (ATP 3-90.4). The breaching force employs all available means to break through or establish a passage through an enemy defense, obstacle, minefield, or fortification. As a general rule, obstacles are covered by fire; a primary role for the FA is to suppress the weapons systems that can engage the rupture force. The staff integrates maneuver, CAS, artillery, mortars, Army aviation, electronic attack, the employment of scatterable mines, air defense, obscuration, and deception to create the conditions for the success of the breaching operation. Additionally, the maneuver force must continue to fight well beyond the breach area to stop the enemy from counterattacking or repositioning to reinforce the enemy unit targeted for penetration. Detecting and engaging the enemy's reserve is a primary concern. The FS planners must carefully balance resource requirements (such as Army indirect fires and CAS) for isolating the point of penetration with the requirements of the element conducting the breach. The breaching fundamentals are suppress, obscure, secure, reduce, and assault. They can be remembered with the memory aid SOSRA.
