differ from the "ZT 1" in having large ventilation grilles at the sides and by a changed back, without stowage box, with a different rear-light and a shortened exhaust pipe. Airborne tank In 1936 the French Army began planning to execute, in case of a war with Germany, offensive airborne operations on the enemy flanks (Netherlands, Switzerland) or hinterland. As no serious artillery support could be given, it entertained the thought of providing fire support to the infantry by airborne tanks, to be landed on captured airfields. A note by the 1er Direction (the Section des Chars de Combat of the Direction de l'Infanterie), dated 18 May 1936, shows that Renault had already begun to study the technical feasibility of such a project. On 26 May 1936 the Renault research bureau offered a possible solution. It proposed to design a light airborne tank, based on the Renault ZT. To save weight several innovative technologies would be applied: the use of light alloys; replacing the original chassis and turret using riveted armour plates with a cast hull and welded dome-shaped turret; the use of sloped armour and finally the use of the turret configuration already in development for the Char G1, featuring a gun mount on the bottom of the tank, obviating the need to install a heavy gun mantlet. By these measures Renault hoped to limit weight to 5040 kilogrammes for a maximum armour of thirteen millimetres or 5400 kilogrammes if the Army desired the higher protection level of twenty millimetres. The height would be 180 centimetres. To make room for a 37 mm gun, the minimal calibre to provide HE fire support, the turret would have a cross-section of 136 centimetres. A hundred shells could be carried and three thousand rounds for the 7.5 mm machine-gun. The crew would be two. As France at the time had no cargo planes large enough that a tank might drive over a ramp into their cargo rooms, Renault proposed to replace part of the bottom of a Bloch MB.300 bomber with a platform on which the Char Léger transportable par avion could be placed; it would have to be lowered and hoisted by cables. No prototype was ever built Operational history Tactical function Due to its name, the AMR 35 has typically been described as a reconnaissance or scout tank but this is inaccurate and possibly misleading. Specialised reconnaissance was carried out,
