To satisfy the historians who want immersion and the regulars who just want to play and don’t care, I suggest doing the same thing that Vanguard is doing which is giving the players the option to choose whether they want historical symbols portrayed or not. This would give both sides what they want without enforcing it on one or the other. As of 2018, there are almost 0 countries that ban the WW2 symbols for educational purposes within video games. If you want to double down, you can just not give the option to specific countries that may still not like it.
A lot of these symbols are already present within the game/game files so I am sure the devs were thinking of doing something similar.
The symbols I refer to are as follows: Iron Cross/Swastika, SS Bolt, Hammer and Sickle, etc.
As they may add the Pacific Campaign it would also apply to as follows: The Red Circle, Imperial Flag of Japan, etc.
These would be from flags to insignia on uniforms/vehicles.
