Challenger 3 for UK
KF51 for tech study and export
Leo 2A8/A9+ for ongoing future upgrades for both domestic and export
MGCS for the Franco-German future Euro MBT project
Leo 3 as probably a ‘Germany-first’ initiative and backup option should the MGCS falls apart
The issue with the Kranvagn is less the turret. Look at the M6A2E1 hull front.
But the major issue is the gun. There never was a gun. Any stats of the gun would be fictional. Also. The T58 is more than reasonable to add as it was a completed prototype.
Though its rangefinder wasn’t mounted here, it’s implied it was later.
