I would like to suggest a couple points of contention as to rework the vehicles in use in the Normandy campaign, and also make suggestions as to potential higher campaign tier vehicle matchups.
Of greatest issue is the M8 Scott - while yes, it does offer similar gun performance to the Pz 3N, it is inferior in most all respects to the Panzer 3. I see very little use of it in game, for reasons that should be obvious to anyone. For those of us who have played warthunder, it’s double a full uptier below the 3N, and is rather obviously unable to contend with it’s adversary.
There are, however, alternate vehicles that could, and I believe should, be considered for the allied side in place of the M8 Scott.
First of all, we have the most historically equivalent allied tank analogs - the Centaur IV, or a 105mm armed Sherman - both of which saw action at D-Day. The 105mm Sherman already being available in Warthunder for use as a model. While arguably marginally better in the context of enlisted due to a larger explosive charge in it’s ammunition, this would be merely a reversal of the relative difference in performance we see with the base vehicles, between the M5A1 and Puma, rather than the sort of disparity currently between the M8 and Pz3N.
If it is the intent of the developer to maintain a performance disparity at this tier with allied vehicles having a disadvantage, then there are still other options that would offer lower performance while being suitable. For these alternatives, I would propose either the Valentine XI, which was used as a command tank by the UK, or the M10 GMC - which while offering greater anti-tank performance, would have worse anti-infantry performance than the M8. Either would be a better match-up in comparison to the Pz3N than the M8. Though these would be less direct competitors than the howitzer examples prior.
Beyond such, I would propose a modification of the campaign tree at higher tiers as well. Considering that I would assume 40 or 50 campaign levels in a more completed tree, and thus at least two more AFV’s would be placed, we would likely see a Panther and a Tiger at the top of the tech tree.
To facilitate this, I would propose as follows; moving the M4A2 up against the Pz IV H, and the M4A3E2 Jumbo to compete against the Tiger, in whichever position it is in.
Against the Pz IV J, there are a few better analogs on the allied side, assuming he M4A2 has been moved up a slot - of which the M18 GMC being the best candidate for such which saw action at D-Day.
Then to compare against the Panther, I would recommend the Sherman Firefly as it’s allied counterpart, or if it is decided to avoid UK vehicles where possible, the M4A2 76 is an option, with such having been available in the UK prior to D-Day, even if it was refused by troops for the invasion itself.
I believe taking such into account would lead to a more balanced AFV meta in the Normandy campaign in Enlisted, and improve the game overall as a result, as well as increase the variety of vehicles present.
