,The principal role of the engineer in ____________ effects is to ensure that tactical
obstacles are integrated with defender fires to disrupt, turn, fix, or block enemy forces
and create effective EAs where the maneuver commander intends to kill the enemy.
Operations in Depth - ✔✔-Weakening the enemy's will
-Preventing the enemy from gaining momentum in the attack
-Employing obstacles
-Constructing fortifications
-Providing mobility to counterattack or reserve forces
-Ensuring that lethal fires are integrated with obstacles to provide desired effects and
planning and coordinating artillery-delivered and tactical aircraft-delivered
SCATMINES
-Identification of key enemy engineer equipment, to include breaching assets
Maneuver - ✔✔-Engineer reconnaissance
-Providing tactical bridging
-Constructing fortifications to include primary and supplementary Battle Positions
-Providing mobility to counterattack or reserve forces
-Advising the commander of impacts on assured mobility caused by lethal fires
Security - ✔✔-Task-organized with Recon & Surveillance Team
-Provides data that contributes to answering the CCIR
-Obstacle reconnaissance
-Emplaces situational obstacles in order to disrupt or delaying enemy attack

, -Developing and executing the survivability plan, deceive enemy by concealing
strengths and weaknesses
Preparation - ✔✔Maximize the inherent strengths of the defense (arrival to the AO first,
defensible terrain, integration of natural and reinforcing obstacles, rehearsal of actions,
etc).
-Emplace tactical obstacles to produce specific effects on the enemy
-Construct survivability positions to allow maneuver units to sustain fight and protect
MC nodes
Disruption - ✔✔Commanders use _____________ to prevent the enemy from massing
combat power and unhinge enemy preparations and attacks.
-Ensures that combat engineering (M/CM/S) functions are integrated into disruption
activities; leverage the capabilities of geospatial engineering to optimize their effects.
-Tactical obstacles are designed and emplaced to disrupt enemy formations and cause
the enemy to move into desired EAs
Flexibility - ✔✔Commanders focus planning on preparations in depth, use of reserves,
and the ability to shift the main effort.
-Using situational obstacles
-Task-organizing for rapid transition to the offense
