GENERAL

Armament and sighting equipment are two classes of equipment.

Sighting equipment are essentially aids to improve the

accuracy and speed of armament firing operations.

All armament systems provide manual back up devices should the

power controlled systems fail.

This chapter provides information primarily intended to overcome armament system

failures.

Sighting equipment, because of their complexity, do not lend themselves to BDR procedures.

Refer to the

standard TMs for sighting equipment repairs.
