NOTES
The M106 carrier is the M113 armored personnel carrier modified to carry the M30 4.2-inch (107mm) mortar on a specially designed
turntable mount. It is an armored, full-tracked, self-propelled vehicle that can swim streams and small bodies of water. A .50 caliber
machine gun is mounted on the cupola for the vehicle commander's use.
To fire the 4.2-inch mortar from the carrier, the top plating to the rear of the carrier has a mortar-hatch cover, which is hinged
and folds to both sides. The carrier provides limited armor protection for the squad during maneuver. In combat, the mortar is fired
with the ramp closed and locked. During firing exercises in training, the mortar may be fired with the ramp open for visual inspection
by safety personnel.
The mortar and its components can be removed from the carrier for ground-mounted firing. The baseplate, bridge, and rotator assemblies
of the ground mount are stowed outside the carrier. A minimum of four mortarmen is required to remove the mortar and standard assembly
from the travel position.
Replaced by the M1064A3 120mm mortar carrier in U.S. service.
