Tanks are placed on terrain features that dominate likely avenues
of approach, permit long range fires, and facilitate covered withdrawal
to the next delaying position. The occupation of each delaying
position is similar to the occupation of a platoon defensive
position (fig. 23). Basic factors which the platoon leader must
consider in occupying a delaying position include:
a. Primary, alternate, and supplementary positions.
b. Preparation of range cards.
c. All-round security.
d. Coordination with other units.
133. Platoon Preparation for Delaying Action
The platoon leader keeps the troop commander informed of the
specific position occupied by the platoon. He ensures that all squads
and sections make maximum use of available time to improve and
strengthen the position occupied by the platoon. Tanks are positioned
in hull defilade, fires are coordinated, and fields of fire are
cleared for all weapons. Individual foxholes and automatic weapons
emplacements are prepared and improved. All positions are camouflaged.
Range cards are prepared for tank weapons, automatic
weapons, and the mortar. Obstacles are constructed and covered
by fire. The position and planned fires are coordinated with adjacent
units. Covered routes of withdrawal are selected and reconnoitered
for each vehicle to the platoon route of withdrawal.
134. Conduct of Platoon Delaying Action
In a delaying action, successive positions are occupied long
enough to cause the enemy to halt, develop the situation, and deploy
for the attack. The platoon leader must keep the troop commander
informed of the platoon situation to ensure receipt of orders for
the platoon withdrawal before it becomes decisively engaged. Contact
with the enemy should be maintained throughout the action.
Elements of the platoon conduct the delaying action as follows:
a. Scout Section. The scout section is employed well forward to
maintain contact and give early warning of enemy approach. It
remains in contact with the enemy and directs supporting long
range fires. As the enemy approaches the platoon delaying position,
the scout section withdraws by squads, normally to the flanks
of the platoon, to positions where they can provide flank security.
Scouts normally remain concealed in position and do not fire
except to defend or extricate themselves. They maintain contact
with the enemy and report any attempt by the enmy to bypass or
envelop the position.
