2-171. To provide flank guard, platoon-size elements from one of the companies in the battalion’s main body provide a moving flank screen under company control. These elements remain at a distance from the main body, allowing the battalion time and space to maneuver to either flank. Flank security elements also operate far enough out to prevent the enemy from surprising the main body with direct fires. Indirect fires are planned on major flank approaches to enhance security.
