Showpiece with excess weight: Ukraine uses Challenger tanks in a special way. The vehicle drums against their fortifications - the success of another counteroffensive depends on British exports.

Only Great Britain and Oman - the latter in very small numbers - use this model.

The British are now considering how they can continue to be combat-ready within the NATO alliance.
