A BMP-2 with no missile is already in-game in form of the BMP-2MD in battle rating 8.7, even if added early versions before the modernisation program, I don’t think the absence of thermal imaging devices will justify such battle rating difference from the base model and improved model (respectively soviet BMP-2 and finnish BMP-2MD) which same applies to a probable finnish BMP-2 (with the 9M113 launcher) will probably have the same battle rating as the soviet brother.
Strv 102 and Strv 104 in my opinion is not needed, would be the same-same with the current vehicles but with—respectively a transition from the older 84 mm QF-20 Pounder cannon to the 105 mm Royal Ordnance L7 cannon with (probably laser rangefinder) yet retaining the weaker Centurion Mk.1 hull armor; the latter would fall under the same situation except would have a improved engine but again, it’s in the game.
Regarding the Strv 103D which I think is the main one here; definitely a no, at least as a Premium vehicle, the early Strv 103-0 is already available, Strv 103D can be easily be added as a folder vehicle since it has major improvements compared to the older Strv 103C. If you want a newer Strv 103 as Premium vehicle, I’d agree with the Strv 103B since it’s just a engine upgrade with minimal changes to the angle of elevation and depression.
About the ZSU-23-2 it would depend on which platform this would be fitted in, depending a lower battle rating would be considered. The BTR-ZD ZSU-23-2 is at battle rating 6.0 and it’s a formidable vehicle with great mobility and firepower, I don’t think a finnish counterpart in a truck bed would be any better given the experience with wheeled vehicle in War Thunder is very frustating at times:
Emil series of tanks lies in a grey zone of vehicles in War Thunder but would be fun to be added, however I doubt it will ever go past battle rating 8.0 except if the proposed 15 cm L/40 is considered for the Emil III/Kranvagn which is the least probable to be added because: It was never built, even the Emil prototype chassis would be incompatible with the Emil III/Kranvagn proposition.
And a about the Leopard 2A4 CHL at battle rating 11.0 I doubt considering it’s a heavy improvement of the base model Leopard 2A4 would have access to better ammunition, and depending how Gaijin implements the thermal coat to ground vehicles this would dictate its battle rating.
