Armoured vehicles are used by a number of corps and units across the armed forces. Units are required to train using a ratio of 1.5 crew operators (drivers) per vehicle against their peacetime establishment. This ratio is different for operational requirements, which is usually set at two crew operators per vehicle.
These ratios may vary depending on the vehicle, however all requirements are currently being met.
