Marine Rifle Squad

(d) The use of voice communications prevents members of the search
party from being surprised and assists the fire team leader in controlling
the search.
(7) When the search team makes entries into subsequent rooms, the entry
will normally be preceded by bursts of rifle fire. If the interior walls of
the building are constructed of heavy (brick or concrete) material, fragmentation
grenades may be used.
(8) The entry and searching process continues until the entire building
is cleared.
(9) When the building is cleared, the fire team leader signals the squad
leader and marks the building according to a prearranged code. The squad
leader moves the covering party forward, protected by the search party.
9107. Techniques Employed
Combat in a built-up area requires the employment of techniques peculiar
to this particular operation. Using these techniques enhances coordination
and ensures accomplishment of assigned missions with minimum casualties.
a. The attack is conducted systematically, block-by-block and section-bysection.
This system reduces the possibility of enemy resistance remaining
active in the rear of advancing units.
b. Coordination of movement between individuals and units is of utmost
importance so that proper covering fire and observation can be provided.
Additionally, the establishment of killing zones down streets and across
open areas requires clOse coordination between units. Whenever streets or
open areas are crossed, the squad leader must coordinate the lifting or shifting
of friendly supporting fires from that street or open area.
c. Built-up areas are ideal for the use of boobytraps. Certain steps may
be taken to avoid them or lessen their effectiveness.
(1) Mark entrances into buildings and rooms used by the search team.
The covering team should use these entrances, since they are known to
be clear.
