Brand "Moteur Moderne", Type 3.M-27, 3 vertical cylinders, 2 stroke, suppressor ignition system, displacement: 8250mm3, cooling system: water, Four torsion bars, Undercarriage: 6 double rollers - fitted on each side with rubber tires - (580mm x 140mm), Shock absorbers: on the 8 extreme rollers, The Batignolles-Chatillon Char 25T was an early Cold War medium tank of France, developed in 1954 by the Batignolles-Chatillon company.

Its primary armament was a 90 mm cannon, and was operated by 4 crew members.

The armor was very thin, being 50 mm at its thickest point, and only intended to protect against heavy machine guns, as that was enough considering the role of the tank being focused on hit-and-run tactics.

It used the same ammunition as the T119 gun used in the American M47 Patton (later designated 90 mm M36) but with a longer barrel, resulting in a higher muzzle velocity of 930 m/s (3,100 ft/s) with a 10.91 kg (24.1 lb) projectile, giving better range and armor penetration with kinetic ammunition.

[4] The tank was also equipped with two 7.5 mm machine guns for close range anti infantry fire and/or estimating the range to the enemy target, as well as four smoke grenade launchers (two on each side) which could be deployed for extra shielding while retreating from a difficult situation.
