Appendix C 210 ATP 5-0.2-1 07 December 2020 C-88. Key events during the forward passage of lines are— Stationary support ends when the combat element of the passing unit—including the reserve— moves beyond direct fire range. Passing unit's reconnaissance assets screen forward of release points. Stationary unit provides security operations along passage lines. Passing unit moves from AA to attack positions. Stationary unit clears obstacles from contact point to passage points. Higher headquarters ideally controls the passage as two parallel chains of command are operating simultaneously in one AO and increased risk of friction exists. Passing unit assumes responsibility for conducting operations beyond the battle handover line (BHL) once the attack begins. Passing unit assumes full responsibility for sustainment forward of the BHL. C-89. The stationary unit furnishes the passing unit with any previously coordinated or emergency logistics assistance within its capabilities. These typically include— Evacuating casualties and enemy prisoners of war. Controlling dislocated civilians. Using areas and facilities such as water points and medical facilities. Controlling routes and traffic management. Recovering disabled vehicles and equipment. REARWARD PASSAGE OF LINES C-90. A rearward passage of lines occurs when a unit passes through another unit’s positions while moving away from the enemy (ADP 3-90). A rearward passage of lines is similar in concept to a forward passage of lines. It continues the defense or retrograde operation while allowing for recovery of security or other forward forces. This operation may or may not be conducted under enemy pressure. C-91. A rearward passage of lines is likely to be more difficult than a forward passage because of the following: The enemy probably has the initiative, which tends to reduce the time available to conduct liaison and reconnaissance and make detailed plans. If the rearward moving force has been in action, its Soldiers are tired and possibly disorganized. The enemy may be applying pressure on the passing force. Friendly forces may be more difficult to recognize because enemy forces may be intermixed with them. Planning a Rearward Passage of Lines C-92. The required support agencies and a tentative location for the unit's trains should be established as quickly as possible. The sustainment assets of the stationary unit should be used to free up some of the passing force's support operations in depth. C-93. Close coordination between the passing and stationary units is crucial to successfully executing the rearward passage and subsequent transfer of responsibility. This is even more critical when the tactical situation results in a staggered or incremental rearward passage across an AO. The passing commander relinquishes control of subordinate elements remaining in contact at the time of the transfer of responsibility to the stationary commander. Generally, the stationary unit assumes control of the AO forward of the BHL after two-thirds of the passing force's combat elements move through the passage points. Figure C-6 shows example graphic control measures used in a rearward passage of lines.
