It is not for us to discuss how the Abrams tanks should be maintained, but the hon. Lady makes an important point: heavy armour can be a liability if we do not ensure it is properly resourced and maintained. That is why we are working at the fastest possible pace to balance the urgent operational requirement of getting this equipment into the field with ensuring that it is an asset, not a liability. We have ensured that not only will the tank crews—who, incidentally, will be already experienced on tanks, albeit of a different type—be selected to be trained, but separate maintenance crews will have the skills and supplies to sustain Challenger 2 tanks in the field and take the fight to the enemy.
