3-176: Plan and Integrate Obstacles

Previous: 3-175: Determine Where to Kill the Enemy

3-176. The following steps apply in planning and integrating obstacles (see figure 3-22) during defensive missions:

Determine the obstacle group intent with the engineer platoon leader confirming the target, relative location, and effect. Ensure intent supports the task force scheme of maneuver.
In conjunction with the engineer platoon leader, identify, site, and mark the obstacles within the obstacle group.
Integrate protective obstacle types and locations within Infantry platoon defensive perimeter.
Ensure coverage of all obstacles with direct fires and or indirect fires.
Assign responsibility for guides and lane closure as required.
According to METT-TC, assist engineer platoons in emplacing obstacles, securing Class IV/V point, and securing obstacle work sites.
Coordinate engineer disengagement criteria, actions on contact, and security requirements with the engineer platoon leader at the obstacle work site.
