SHOULD THE POINT PERSON ENGAGE A TARGET DURING THE PIE, BOTH MARINES IMMEDIATELY ASSAULT THROUGH THE WINDOW OR MOVE TO WHERE THEY CAN TAKE OFFENSIVE ACTION. Figure A-11. Alternate Technique for Moving Past Windows 8. Movement Parallel to Buildings. Marines and small units may not always be able to use the inside of buildings as a route of advance. In such cases, they should move on the outside of the buildings (Figure A-13). Smoke, covering fires, and cover and concealment should be used to hide movement. When correctly moving along the outside of a building, the Marine hugs the side of the building, stays in the shadow, presents a low silhouette, and moves rapidly to his/her next position (Figure A-14). If an enemy gunner inside the building fires on a Marine, he/she exposes himself/herself to fire from other squad/fire team members who are covering him/her. Furthermore, an enemy gunner farther down the street may have difficulty detecting and engaging the Marine. A - 10 MCWP 3-35.3
