(Divisions d'Infanterie Motorisée), each had an antitank-platoon with two ZT2's and two ZT3s. Five AMR 35 were present in the driver school at Saumur; eight were in the general matériel reserve. Of the ten Renault YSs, four were used by the Cavalry, four by the Infantry and two by the Artillery. The Renault YS 2 prototype, despite not being made of hardened steel, was deployed by the 71e RA, the artillery regiment of 2e DLM. During the battle the 13.2 mm machine-gun proved to be incapable of defeating even the German armoured cars at normal combat ranges, its bullets being deflected by their sloped armour. However most AMR's were lost due to mechanical trouble. All vehicles assigned on 10 May had been lost by the end of the month. In June, an ad hoc-unit was created, the 7e DLM and part of this was the 4e RAM (Régiment de Automitrailleuses) that used some AMR 35s taken from the matériel reserve. German use The Germans used some AMR 35s as the Panzerspähwagen ZT 702 (f); the Renault YSs were also taken into service. The ZT4s, being brand new, were partly fitted with the 8cm schwerer Granatwerfer 34/1 in an open superstructure to produce a self-propelled 81 mm mortar; some received the AVIS-1 turret. Most of these vehicles were used by the occupation forces in France. Certain number (circa twelve including at least one mortar-equipped vehicle) were used by Panzerkampfwagen-Kompanie 539 in Prague for occupational duty in protectorate Böhmen und Mähren. In May 1945 three ZT4s had been captured by the Czech resistance and turned against their former owners.
