Do not swim carrier. Injury to personnel and equipment may occur. The M548A1 and M548A3
carriers can ford water up to 40 inches (107 cm) deep. However, these carriers do not swim. Do
not try to enter water known to be deeper than 40 inches (107 cm).
The M548A1 and M548A3 6Ton Tracked Cargo Carriers are lightweight and unarmored. They are full-tracked cargo
carriers for use as cargo and ammunition support carriers. These carriers can cross small streams and cross rough ground, and
move over roads and highways. They can be air-transported. A full width cab provides enclosed seating for the driver and
three passengers. The following pages provide: information on various kits and equipment, a series of illustrations showing
the Location and Description of Major Components, and a detailed list of the Differences Between Models. See the table of
Equipment Data at the end of this section for a list of important carrier data.
The terms right, left, front, or rear are used in this manual to describe areas and parts of the carrier and their location relative
to each other. The terms are used the same way you would use them if you stood at the cargo door end of the carrier and
looked toward the cab.
MATERIEL USED WITH CARRIER
Various kits and equipment can be applied to the M548A1 and M548A3 carriers to prepare them for particular missions or
operating conditions. The individual kits are listed below. If you have one or more of these kits, be sure to check your
Preventive Maintenance Checks and Services (WP 0057 00).
MATERIAL HANDLING KIT
Required for ammunition support. The kit includes a hand-operated chain hoist on an overhead beam, a plywood protector for
the power plant compartment bulkhead, and seats and seat belts in the cargo compartment for four ammunition handlers. The
kit also provides stowage for six rifles on the cargo compartment door. See Material Handling Kit illustration under Location
and Description of Major Components. See Equipment Data table for details.
AIR BRAKE KIT (M548A1)
Required when the carrier is used as a prime mover for towed equipment that has air brakes. The kit includes a compressor
and air tank, air hoses, a pressure gauge, and a treadle valve. See Air Brake Kit illustration under Location and Description of
Major Components. See Equipment Data table for details. The M548A3 carrier is unable to use this kit because of a different
TURN SIGNAL KIT
Required in some areas when the carrier is to be driven on roads or highways. The kit adds front signal lights and brackets, a
control unit, a flasher, and reflectors, and changes the tail lights. See Turn Signal Kit illustration under Location and
Description of Major Components.
