The AMX-13/75 FL-10 (HOT) is the fourth subvariant of the AMX-13/75 FL-10, which is the first variant of the AMX-13 light tank family. Except for the six HOT anti-tank guided missiles (ATGMs) installed on two launchers next to the turret, it is similar to the standard AMX-13/75 FL-10. The HOT (Haut subsonique Optiquement Téléguidé Tiré d'un Tube) is a second-generation long-range ATGM. It was designed to replace the older SS.11 wire-guided ATGMs used in French and West German service. The design was created in partnership with the German company Bölkow and the French company Nord. HOT ATGMs have a greater range, higher flight speed, and are semi-automatically guided rather than manually guided like SS.11 ATGMs. It has become one of the most successful missiles in its class, with tens of thousands of missiles manufactured, utilized by more than a dozen countries throughout the world, and deployed in several wars.

Introduced in Update 1.75 "La Résistance", the AMX-13/75 FL-10 (HOT) features the same playstyle as the standard AMX-13/75 FL-10. This light tank is exceptionally fast and agile, but it does it at the expense of its armour. However, this light tank encounters far more advanced opponents than its predecessor, the AMX-13/75 FL-10 (Char Lance SS.11). As a result, despite being a light tank with a powerful main gun, it struggles to penetrate most adversaries in combat. Instead, it must rely on the six HOT ATGMs to eliminate foes at great ranges. The HOT ATGMs are incredibly effective against even the most protected opponents. It is recommended that it be used as a long-range tank destroyer, with its superior ATGMs picking off enemies over great distances. The primary armament should be used only when the enemy is revealing its sides without paying attention.
