While there are several accounts of German tank strengths in NW Europe, figures for British units are not as common.
Some references say what type of tank they had, but more detailed records are harder to find.
This series of documents, charting events in the RAC which covered all armoured units in the British Army, has a mass of details on organisation, training, vehicle development and related subjects. Early reports were short, but by the war's end a report was several inches thick, with extensive appendices covering figures. Produced each June and December, they cover the previous six months. Copies of these reports are available in the library of the Tank Museum at Bovington, and also the UK official archives, the Public Record Office in Kew, London. The following article should show something of what British tank units had in the way of equipment.
