Section III. PRINCIPLES OF OPERATION
M3 CROP NORMAL OPERATION.
The M3 CROP is equipped with an end structure assembly capable of being pinned in the upright position for normal oper-
ation and placed horizontally for stacking. All components are permanently attached to the M3 CROP with the exception
of BII, center and rear blocker assemblies, end structure assembly, twistlocks, rollers, stowage box doors, and bracing
mechanisms. Refer to TM 9-2320-364-10 for PLS flatrack loading/unloading procedures.
BII are stored in the stowage boxes located in the cargo deck. Prior to stacking, the blocker assemblies must be removed
from their normal positions and secured in their stowed positions. The center blocker assembly is removed from its normal
position just rear of the end structure assembly and secured longitudinally on either side of the cargo deck approximately
18 inches (46 cm) from the front of the M3 CROP. The rear blocker assemblies are removed from their normal positions at
the rear of the cargo deck and secured longitudinally, each on its respective side of the cargo deck approximately 30 inches
(76 cm) from the rear of the M3 CROP. The end structure assembly is normally in the upright position, but is positioned
horizontally on the deck for stacking. The twistlocks, rollers, stowage box doors, and bracing mechanisms remain attached
except for maintenance and replacement.
