So, the M4A3E2s already had track extensions modeled ever since they were added, even though there are pictures IRL where they don’t equip them.
Now, with the upcoming premium packs for the US and Britain, the US is getting an M4A3 with track extensions and Britain is getting a Firefly with track extensions.
However, the track extensions on these vehicles aren’t modeled as modifications, so vehicles like the normal M4A3 and Firefly and other Shermans (M4A2 75 etc.) don’t get them, despite Germany getting Winterketten and Ostketten as a modification on practically every vehicle that uses the Panzer 3 and 4 chassis.
So, I just want to know why aren’t these made as modifications so tech tree variant can receive the track extensions as well, especially since another country already has this mechanic?
