B-46: Restrictive Fire Line

Previous: B-45: Maximum Engagement Line

B-46. An RFL is a linear fire control measure beyond which engagement is prohibited without coordination. In the offense, the platoon leader can designate an RFL to prevent a base-of-fire element from firing into the area where an assaulting element is maneuvering. This technique is particularly important when armored vehicles support the maneuver of rifle squads. In the defense, the platoon leader may establish a RFL to prevent the unit from engaging a friendly rifle squad positioned in restricted terrain on the flank of an avenue of approach.
