Introduction. This introduction provides a general explanation of all maintenance and repair functions authorized at
various maintenance levels under the standard Army Maintenance System concept.
The MAC (immediately following the introduction) designates overall authority and responsibility for the performance of
maintenance functions on the identified end item or component. The application of the maintenance functions to the
end item or component shall be consistent with the capacities and capabilities of the designated maintenance levels,
which are shown on the MAC in column (4) as:
Unit - includes two sub columns, C (operator/crew) and O (unit) maintenance

The tools and test equipment requirements (immediately following the MAC) list the tools and test equipment (both

The remarks (immediately following the tools and test equipment requirements) contain supplemental instructions and
explanatory notes for a particular maintenance function.

Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical
characteristics with established standards through examination (e.g., by sight, sound, or feel).
Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics of an item
and comparing those characteristics with prescribed standards
Service. Operations required periodically to keep an item in proper operating condition, e.g. to clean (includes
