Description
Technical Manual Change 1 (TM 9-1240-266-35) for M14 Reticle Image Projector May 1969 FSN 1240-572-8739
This Technical Manual Change 1 for TM 9-1240-266-35 updates the field and depot maintenance manual for the M14 Reticle Image Projector and is dated May 1969. The documented projector is identified by FSN 1240-572-8739.
The M14 was used in the M60A1 tank fire-control system, where it worked with the gunner's M35 periscope to project reticle data into the sight. Change 1 applies to the original manual issued on April 7, 1966 and is not the complete base manual.
Historical Significance
The M14 belongs to a generation of U.S. Army tank fire-control equipment that combined precision optics with electrical and mechanical components. In the M60-series sighting system, the M14 worked with the M35 periscope to provide internal projection of reticle data for the gunner.
The M60A1 used this type of optical fire-control arrangement as part of its gunner's sighting system. Issued three years after the base manual, this May 1969 change notice records the continuing maintenance history of an important component in that system.
M60A1 Tank Fire-Control Application
The M14 Reticle Image Projector was associated with the M35 gunner's periscope used in the M60-series tank fire-control system, including the M60A1. The projector supplied internally projected reticle data within the sighting arrangement.
This relationship places the M14 within the tank's optical fire-control equipment. The projector supported the gunner's visual aiming reference; it was not a general-purpose image projector.
What This Manual Covers
This publication provides the Change 1 updates issued for the M14 Reticle Image Projector field and depot maintenance manual. Its scope is limited to revised material for TM 9-1240-266-35 rather than a full restatement of the manual.
The associated base publication covers maintenance of the electromechanical M14 projector used with the M35 periscope in M60A1 fire-control equipment. The complete maintenance coverage remains in the original April 7, 1966 manual.
