It’s the most recognizable British tank in my eyes. I know it’s 1944, but the British will be forgotten by the time they introduce the Soviets, Americans and Japanese. Equivalent to a Panzer IV. We do not have a medium tank for the British.
In the beginning it’s a Cromwell, with a path to make it into a Comet.
I don’t see an issue, a Panzer IV can be upgrade with a KwK 40 L/48 cannon, armor. The only difference the Britsh changed the name, the Germans didn’t.
The Germans did, it just typically wasn’t a totally new name. They stuck letters on the end to denote the variant if it wasn’t a major alteration. They would change the name, leaving some portion of it unaltered, if it was a more major alteration. (eg the StuGs and Sturmpanzers)
If they do add the Cromwell, I see no problem with using the Comet as one of the upgrade paths, so long as they give other tanks the same treatment.
They were substantially different, and the entire turret and the all-important gun were entirely different. The British were not shy about up-gunning their tanks while keeping the same name for different marks, so why would they not do the same with the Cromwell unless they considered the new design so different it justified a new name? The Cromwell was another in a long line of British tanks that were effectively obsolete when new, a stopgap until something better was available. The Comet was the first well-balanced tank design Britain came up with in WWII, it deserves its own name.
