None of the allocated days have been used for firing of the Challenger tank 120 mm guns since 2001. However, as there are only two other ranges suitable for main battle tank (MBT) use—Lulworth and Castlemartin—and given the critical requirement for MBT crews to fire during pre-deployment training, the Warcop facility remains a strategic reserve asset for use in the event of one of the other ranges being unusable.
