The armoured cars themselves only began to arrive late February. This delay was used to give a first general driver training to the crew-members, the vast majority of whom did not possess a driver licence, as prewar car ownership had been relatively low in The Netherlands. At first even for this no vehicles were available and an attempt to give basic infantry training instead, failed for lack of rifles. After a few weeks old Dutch Eysink motorcycles could be used — each platoon also would have a motorcycle squad — and then some modern German BMW motorcycles. Also the old "Bison" and "Buffel" armoured cars were used, that in 1932 had been built by the Ordnance Department on the chassis of Morris trucks to assist the security forces in suppressing riots during the Great Depression. The first five DAF M39s received were incomplete lacking armament; they were only used for theoretical instruction before being taken away to be equipped with their cannon. In March they became available again, of one vehicle in the meantime the armour cracks had been repaired by DAF. However, they still lacked machine-guns, gunsights, ammunition stowage and many smaller other fittings and therefore were only usable for driver training; gunnery training was postponed. Most of the training took place at or near The Hague. In April the commander of the Cavalry Depot concluded that under these conditions at best a single platoon could be ready on 1 July and all four no earlier than 1 September.
