Maintenance, when properly performed, helps to ensure that
equipment will perform the mission for which it was designed.
By virtue of the dangerous cargo transported by the M992 carrier, an

are a necessary ingredient for mission accomplishment, the Automatic Fire
Extinguisher System installed on the M992 Ammunition Carrier, is an
important system which must be maintained to ensure personnel and equipment
safety are not jeopardized.
The Self-Propelled Field Artillery Turret
Mechanic, MOS 45D, properly trained and motivated, is the individual who is
ultimately responsible for ensuring the M992 AFES is functional and ready to
do the job for which it was designed.
Therefore, maintenance personnel must be knowledgeable in the proper use of
technical manuals (TMs), basic principles of equipment operation, applicable
safety procedures, and the application of the inspection, maintenance, and
testing procedures applicable to the equipment being maintained.
lesson you will acquire this knowledge as it applies to the Automatic Fire
Extinguisher System installed in the M992 Carrier, Ammunition, Tracked.
Organizational maintenance is accomplished as outlined in TM 9-2350-267-20.
PART A - INTRODUCTION TO THE M992 CARRIER, AMMUNITION,
The M992 Carrier, Ammunition, Tracked is a field artillery ammunition
support vehicle and is comparable in terms of speed, mobility, and
survivability to the M109A2 family of artillery weapons which it supports.
The M992 is a full-tracked, self-propelled, diesel powered vehicle and is
highly mobile and maneuverable.
This vehicle transports 155mm artillery
projectiles and charges from ammunition depots and supply points to the
howitzers in field locations.
The M992 features ammunition handling
equipment (AHE), which includes a hydraulically-operated conveyor, stacker,
and projectile rack assemblies which have a stowage capacity of 90 155mm
An Auxiliary Power Unit (APU) is another feature of this
The APU supplies enough power to run the M992 electrical system
and that of a supported vehicle via use of slave cables and receptacles.
The APU also powers the primary hydraulic pump which supplies hydraulic
fluid to all hydraulic circuits.
