Marine Rifle Squad

d. Release Point. Release points are clearly defined points on a route
where units are released to the control of their respective leaders.
e. Probable Line of Deployment (PLD). The probable line of deployment
is an easily recognized line selected on the ground where attacking
units deploy in line formation prior to beginning a night attack.
f. Limit of Advance. A line of advance is generally designated beyond
the objective to stop the advance of attacking units. It should be easily
recognizable in the dark (a stream, road, edge of woods, etc.) and far
enough beyond the objective to allow security elements space to operate.
4503. Security Patrols
Members of the squad may be used as security patrols to assist night attacks.
These patrols maintain security on the PLD, eliminate enemy security elements,
and prevent attacking forces from being ambushed while en route
to the PLD. They may also act as guides to lead units forward from the release
points to the PLO.
4504. Preparatory Phase for the Night Attack
Preparation for the night attack is generally the same as for the daylight
attack. The squad leader will follow the same format outlined in appendix
C when preparing for and executing assigned missions. Special emphasis is
placed on —
• Reconnaissance by squad and fire team leaders to locate assigned control
features and terrain features for night orientation. Such reconnaissance
should be conducted during three conditions of visibility: daylight,
dusk, and dark.
• Rehearsals conducted both during daylight and darkness. Rehearsals
should include formations, audible and visual signals, and the actions
of the squad from the assembly area to the objective.
• Carrying only that equipment absolutely essential for the success of the
attack.
