The Army Maintenance System MAC
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 subcolumns, C (operator/crew) and O (unit) maintenance

General Support - includes an H subcolumn
Depot - includes a D subcolumn
The tools and test equipment requirements (immediately following the MAC) list the tools and test
equipment (both special tools and common tool sets) required for each maintenance function as

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

characteristics with established standards through examination (e.g., by sight, sound, or feel.)
