DVR – driver
A driver was a soldier trained in the management and use of horses. The six horses drawing the gun, or wagon, were driven by three drivers, all on the nearside horses, and much training was required before drivers would be rated as competent. The drivers, of course, also looked after the horses and the management, condition and state of health of these animals was regarded as one of the most important functions in the battery.
All branches of the artillery used horses, not just the RHA. By WWII, mechanisation had replaced the horse but the gun limbers, lorries and self-propelled guns all required drivers and the rank remained.
The number of horses meant specialist roles of saddler, farrier, and shoeing smith were used and added to the name of the rank. Horse-drawn equipment needed wheelers and fitters and the officer needed clerks who could write in artillery code and signallers who could send it.
