This chapter is for your use in operating and maintaining the M106A2, M1064, and
M125A2 Mortar Carriers. If you do not find an item here, look in Chapters 1
through 3 covering the M113A2 Carrier. This chapter must be used with Chapters
1, 2, and 3 to get the full picture on the M106A2, M1064, and M125A2.
The M106A2, M1064, and M125A2 are built from the same plans as the M113A2
except they have 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 stowage racks
are inside the mortar compartment.
The mortar misfire procedures, operations, maintenance, and ammunition for use
on the carriers are found in operator manuals. Operation of the 107-mm, 4.2-inch
mortar, M30, used on M106A2 Carriers, is covered in TM 9-1015-215-10.
Operation of the 81-mm mortar, M29A1, used on M125A2 Carriers, is covered in
TM 9-1015-200-10. Operation of the 120-mm, 4.7-inch mortar, M121, used on
M1064 Carriers, is covered in TM 9-1015-250-10.
