Heller 30322 FCM36 1:35

The FCM 36 is a small vehicle, 4.46 m long, 2.20 m high and 2.14 m wide, with a crew of two. It has a weight of 12.35 metric tons. The armour consists of many panels electro-welded together into an pyramidal shape to avoid shot-traps and fully implement the principle of sloped armour. Such a configuration was unique at the time. This included the upper track run and the suspension units, protected by zig-zag armour plates. The engine deck is the only armour which is bolted as this enables easier access to the engine. As the armour is of good quality, the 40 mm thickness angled at 30 to 45 degrees from the vertical, renders an equivalence of about 45–55 mm, enough to regularly defeat the standard anti-tank guns of its day, even when the gun was ideally positioned. The reclining armour implied that more raking shots would quickly start to deflect. The type was the only actually produced French tank of the period that featured a diesel engine, which gives the vehicle a superior range of 225 kilometres from a fuel tank of 217 litres.

The Germans captured 37 FCM 36s, using the administrative designation Panzerkampfwagen 737 FCM (f) for them. After some improvised use by units in May and June 1940, they were not as such employed by them. In 1943 ten were rebuilt as Marder I tank destroyers, with the 75 mm PaK 40 anti-tank gun and officially called 7.5cm PaK40(Sf) auf Geschützwagen FCM(f). These were employed by 21 Panzerdivision in the Battle of Normandy in 1944. Twelve were in 1942 rebuilt as self-propelled artillery, the 10.5 cm leFH 16/18 (Sf) auf Geschuetzwagen FCM (f).
