The TR-65 and TR-68 Rammah (رماح, English: Lancer) are Riysian main battle tanks of the second generation, replacing the first-generation TR-56 Fateh. Created on the basis of the T-62 tank mixed with domestic engineering solutions and other foreign components, they are commonly referred to collectively as the "T-62R" series of tanks. From 1965 to 1985, around 680 TR-65s and 3,780 TR-68s were completed.

Protection

The TR-65 and TR-68 have a classic all-steel protection scheme, similar in layout to the TR-56, but revised with thicker armor. With the TR-65/68 being intended to be used in an offensive, MBT-like multipurpose role, significant emphasis was placed on making the new medium tank resistant to the latest tank guns and ammunition. Despite the widespread belief that shaped charges rendered heavy armor obsolete, having a high level of protection was still considered important due to AP ammunition remaining the most common threat.

As defined in development, the primary objective was to resist APDS shots from the 105 mm guns just entering service, at combat distances of at least 1,000 meters, and allow for a field of maneuver of at least 30° off-center. Using the L28A1/DM13/M392 as a representative round, such a shot would penetrate 300 mm of armor steel perpendicularly and 120 mm of steel angled at 60° from the horizontal.

Armor characteristics
Tank section Armor thickness Angle
Upper glacis 135 mm 60°
Lower glacis 132 mm 50°
Side hull 80 mm (+ 20 mm HHS sideskirts on TR-68) -
Rear hull 45 mm
Hull top Up to 30 mm -
Hull bottom 20 mm -
Turret front 275 mm 20°
Turret sides 165 mm (175 mm on TR-68) -
Turret rear 65 mm -
Turret roof Up to 54 mm -

Based on official data, the upper glacis plate of the TR-65 and TR-68 has a thickness of 135 mm and is angled at 60 degrees, and the lower glacis plate is 132 mm thick and is angled at 50 degrees. The turret is as thick as 275 mm with a slight angle of 20 degrees at its front, and with its heavy sloping and optimized shape, a similar level of protection is maintained throughout the frontal arc. Thus

For the sides,

With this level of protection, . Even when faced by the most advanced generation of APDS, represented by the L52 series, the TR-65 and TR-68 remain a formidable opponent.

Against

As a consequence however, the tanks dedicate a significant amount of weight to armor - around 19.3 tonnes for the TR-65, and 19.5 tonnes for the TR-68. This makes up about 51-52% of the total weight for both production versions.


Around 19.3 tonnes of mass comes from the steel armor, for over 50% of its total weight - also the TR-56, but
