Description
Technical Manual (TM 9-1240-239-35P) for M28, M28C, and M28D Tank Periscopes January 1970
This Technical Manual TM 9-1240-239-35P covers the M28, M28C, and M28D Tank Periscopes and is dated January 1970.
The publication is a direct support, general support, and depot maintenance repair-parts and special-tools reference for personnel maintaining these armored-vehicle optical sighting instruments.
Historical Significance
The M28 family represents the specialized optical sighting equipment used across several Cold War-era U.S. armored fighting vehicles. These monocular periscopes served as components of vehicle fire-control systems, giving crews a protected sighting path from inside the vehicle.
By January 1970, the M28, M28C, and M28D variants supported a diverse group of tanks, armored carriers, self-propelled mortars, and mechanized flame-thrower vehicles. This publication preserves the Army's maintenance-supply structure for those related optical instruments.
Periscope and Vehicle Applications
The M28-series periscopes documented in this manual were associated with several distinct armored-vehicle applications:
- M28: used with the M59 armored personnel carrier equipped with the preferred M13 cupola, the M84 4.2-inch self-propelled mortar, and M48A1 and M48A2 tanks
- M28C: used with M67A1 and M67A2 mechanized flame throwers, M48A2C and M48A3 tanks, and M60 and M60A1 tanks
- M28D: used with the M132 and M132A1 self-propelled flame throwers
What This Manual Covers
This -35P repair-parts and special-tools manual supports direct support, general support, and depot maintenance of the M28, M28C, and M28D Tank Periscopes. It provides the official parts-identification and supply reference needed to locate components and plan higher-level maintenance support.
The manual covers three related periscope variants under their individual Federal Stock Numbers and is focused on repair parts and special tools rather than operator-level use or basic vehicle operation.
