TROOP CONSIDERATIONS
6-82. At troop level, the passage of lines is usually performed as part of the squadron or IBCT. The
passage may be forward, such as to pass through a defending unit to conduct a zone reconnaissance, or
rearward, such as when a screening force unit withdraws through units in the main battle area.
6-83. The troop is particularly vulnerable during a passage of lines. The unit may be concentrated and the
fires of the stationary unit may be temporarily masked. Furthermore, the possibility of fratricide increases
considerably. Thorough reconnaissance and detailed coordination are critical to ensuring the operation is
successful.
6-84. The troop commander has numerous critical tasks to ensure a successful passage of lines. During
reconnaissance, he confirms the following:
The disposition of the stationary force through which the troop will pass.
The location of contact points where both units are required to make physical contact at a
predetermined time.
The location of passage points on the BHL through which friendly forces will pass.
The location of passage lanes that provide a clear route through friendly positions to facilitate a
smooth and continuous passage. Areas selected for passage should be unoccupied or on the
flanks of units in position. If possible, multiple routes are used to reduce vulnerability during
the operation.
The location of a screen line (for forward passage) or assembly area (for rearward passage).
The initial location for enabling and sustainment elements.
6-85. Based on the reconnaissance, the DRT commander coordinates and plans for the following:
Fires. The stationary force supports the passing unit with direct and indirect fires up to the
BHL. In a forward passage, the stationary force supports the passing unit’s move through the
passage lane until it crosses the BHL. In a rearward passage, the stationary unit supports the
passing unit’s move back across the BHL and through the passage lane.
Time factors. The DRT commander determines and/or coordinates the time of transfer of
responsibility for control of the AO and handover of the enemy.
Troop density. The passing troop commander plans for multiple routes of passage to ensure
rapid movement and to avoid congestion.
