Lesson 1/Learning Event 1
This level has two categories: intermediate direct support (IDS) maintenance
and intermediate general support (IGS) maintenance, as follows:
The IDS maintenance units are employed at different locations, but the tasks
performed are the same. These units are found in the brigade, division, and
IDS maintenance units provide backup maintenance support to divisional
This type of maintenance is characterized by repair,
replacement, high mobility, forward orientation, and maintaining a high-
volume, fast-moving operational readiness float (ORF). Units can be readily
organized into teams to support specific systems and to project support
forward on the battlefield. Suitcase-type automatic test equipment (ATE) is
used to support BDAR. Repair parts stockage is based on a combat authorized
stockage list (ASL).
Divisional IDS maintenance units are structured to
provide dedicated support to brigades and battalions. This includes repair
of selected high-usage components for DX.
Repair times generally do not
exceed 36 hours.
The IGS maintenance units are located behind the corps and provide support
to the theater supply system through repair of class VII and class IX items.
Their work is job or promotion-oriented and is performed by modular units
with commodity-oriented platoons in semifixed facilities.
Teams may be
added to provide an area support capability as required.
Support (GS)-type ATE is used to support operations.
The IGS maintenance
units do not have an ASL; however, they maintain a shop stock as required
for assigned missions. The units maintain theater reserve stocks in overall
support of theater requirements.
Maintenance at this level is production-line oriented and is performed in
support of the supply system.
The unit missions support overseas propositioning of materiel
configured to unit sets (POMCUS), repair cycle float (RCF), and war reserve
Repair parts supply support for depot maintenance is limited to
items to support assigned maintenance missions.
