5-96: Rearward Passage of Lines

Previous: 5-94: Forward Passage of Lines

5-96. Because of the increased chance of fratricide and friendly fire during a rearward passage, coordination of recognition signals and direct fire restrictions is critical. Rehearsals and training can help reduce fratricide and friendly fire. The passing unit contacts the stationary unit while it is still beyond direct fire range and conducts coordination as discussed previously. Near recognition signals and location of the BHL are emphasized. Both passing and stationary unit can employ additional fire control measures, such as RFL, to minimize the risk of fratricide and friendly fire. (See figure 5-11.)

5-97. Following coordination, the passing unit continues tactical movement toward the passage lane. The passing unit is responsible for its security until it passes the BHL. If the stationary unit provides guides, the passing unit can conduct a short halt to linkup and coordinate with them. The passing unit moves quickly through the passage lane to a designated location behind the stationary unit.
