In September training within the Cavalry Arm was assigned to the newly formed Cavalry Depot, that after a short mobilisation phase at Amersfoort was moved to The Hague as had been prearranged in the "Case Blue" concentration plan. Conscripts should now be quickly trained to form active units. In November the first professional personnel arrived, officers and NCOs, destined for the four DAF M39 platoons. DAF had been asked to provide a two-month training course for about thirty men at the factory itself, but the company vehemently objected. The Ordnance Department concurred: the training should take place at its facility at Delft, the same location the cars were to be completed with armament. For this purpose it prepared a special DAF M39 manual, creating a first draught, the "Ontwerp Beschrijving van de Pantserwagen M. 39", the final version of which however, would not be ready in time to be published. In January 1940 140 conscripts arrived to be trained in the use of the M36 and M38. As the units employing these types were already at strength, these men were diverted to the, much shortened, M39 training, to eventually raise four platoons, hoped to be ready on 1 July 1940.
