Areas filled with intelligent munitions allow free passage by friendly forces and coordinated attack on the enemy. Ground robotics systems take the soldier out of harm's way in especially dangerous situations. Engineers predict requirements and base responses on simulated dynamics in a virtual world. Engineer headquarters mass efforts precisely, monitor execution, and make changes on the move. The four functions also encompass engineer support in defensive areas and combat service support areas as well as the requirement for engineers to fight as infantry when necessary.
Detailed descriptions follow.
The engineer force modifies, overcomes, and uses terrain so the commander can fight where he feels is best for a quick, decisive victory while eliminating as many casualties as possible. This engineer support allows the maneuver commander to focus on tactical operations and frees him from terrain constraints. Force XXI units will rely on mobility to quickly overcome the enemy. Keeping his maneuver forces mobile is a key concern for the commander, and his ability to decide where and when to move should be unrestricted. Using the terrain as a weapon against the enemy enhances the commander's ability to mass fires for an overwhelming decision.
