M1064 MORTAR CARRIER
The M1064 is built from the same plans as the M113A2 except it has a reinforced rear hull floor for firing the mortar. A
three-piece hatch cover folds back on the carrier roof and opens up the hull to fire the mortar in an elevated position. The
turntable directly under the hatch allows the mortar to be fired left and right of the carrier center line. Ammunition and fuze
storage racks are inside the mortar compartment.
