F-74: Fire from a Defilade Position

Previous: F-73: Leader’s Rule

F-74. Defilade positions protect gunners from frontal or enfilading fires. (See figure F-19, page F-26.) Cover and concealment may not provide the gunner a view of some or all of the target area. In this instance, some other member of the platoon or squad must observe the impact of the rounds and communicate adjustments to the gunner. (See figure F-20, page F-26.) Gunners and leaders must consider the complexity of laying on the target. They also must take into account the gunner’s inability to make rapid adjustments to engage moving targets, the ease with which targets are masked, and difficulty in achieving grazing fires for an FPL.
