[2023] Swing and a Miss - Centurion Mk. II

This is explained within the blog:

We are very much aware the Mk II never served in the Korean war and never claimed that the tank did. That's why it has all the standard historical camps available to it as well for those that want that. The additional extra special camo is purely an extra reward.

There is nothing actually wrong with the tank itself, so it's a little bit of an overdramatic title for that thread as the main issue is some mistakes in the additional special skin decals, which are already in the process of being corrected.
