The Char léger modèle 1935 (Hotchkiss) H modifié 39 is a heavily upgraded Char léger modèle 1935 (Hotchkiss) H cavalry tank from 1939. Since cavalry units sought a faster tank, it was decided in October 1936 to modernize its current tanks by installing a more powerful engine. In 1937, a new prototype with a 120 hp engine was created in place of the 78 hp engine. The hull was stretched to provide enough space to accommodate it, resulting in a taller, nearly level engine deck. Aside from episcopes, tails, and various radio sets, this included the gradual introduction of a larger 37 mm SA38 L/35 tank gun with much improved anti-tank capabilities, providing 30 mm of armour penetration at 1 km.

Introduced in Update 1.75 "La Résistance", the Char léger modèle 1935 (Hotchkiss) H modifié 39 is vastly improved over its predecessor. It has a slightly superior main armament, thicker armour overall, and a substantially more powerful engine, which makes it surprisingly fast on flat ground. Nonetheless, as compared to adversaries from other nations, this vehicle remains below average. While it travels quickly in a straight line, it goes slowly over muddy terrain, and its narrow tracks considerably slow it cross-country. It is best employed as a close support tank in urban environments, following teammates while waiting for a good firing opportunity at the enemy.
