The Batignolles-Chatillon Char 25t was a French early Cold War tank developed by the Batignolles-Chatillon company in 1954. The vehicle was never developed further than the two prototypes. It was built for a weight class of 25 tons, which is approximately double the weight of the AMX-13 light tanks. It was armed with a 90 mm D.911 APX tank gun and was manned by four crew members. Its top speed is 65 km/h. Despite the project being abandoned, several of the design ideas and technology were applied to subsequent French armoured vehicles. It never saw duty with the French Army.

Introduced in Update 1.81 "The Valkyries", the Char 25t is a fast tank with minimal armour, so it is important not to engage enemy tanks in frontal combat. It is strongly encouraged to take full advantage of its superb mobility for flanking manoeuvres during battle. The tank also has an acceptable reverse speed, allowing it to quickly disengage after firing. The Char 25t can engage all but the heaviest targets at close range, while at range, it can successfully hit targets from the flank. Players using the Char 25t should always stay out of the enemy's direct line of fire. The Char 25t, like other French light tanks, has a low-profile tank with a tiny autoloader turret in the back.
