INTRODUCTION
The Army Maintenance System MAC
This introduction provides a general explanation of all maintenance and repair functions authorized at the
two maintenance levels under the Two-Level Maintenance System concept.
This MAC 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 level,
which are shown on the MAC in column (4) as:
Field –- includes two columns, Unit Maintenance and Direct Support maintenance.
The Unit
maintenance column is divided again into two more subcolumns, C for Operator or
Crew and O for Unit
maintenance.
Sustainment –- includes two subcolumns, General Support (H) and Depot (D).
The tools and test equipment requirements list the tools and test equipment (both special tools and
common tool sets) required for each maintenance function as referenced from the MAC.
The remarks contain supplemental instructions and explanatory notes for a particular maintenance function.
