Night Sight Maintenance Concept.
Like other systems and equipment, the night sight has a three level
concept for maintenance.
Those levels are: Unit, intermediate
(DS/GS), and depot.
The following paragraphs will explain the
different levels, and what services each level performs.
Unit Maintenance.
Unit maintenance is the maintenance performed on a piece of equipment
by the using unit, and includes:
Doing checks and operator adjustments.
Spot painting.
General cleaning of equipment.
Handling
boresight adjustment procedures (Aline night sight
with the optical sight).
Notifying direct support to perform the 180 day verification
check.
