Some tanks allready have track add on armor in game and i am suggesting it for more vehicles.
Historically many crews added tracks and other spare parts on the front of the vehicle to get more protection, how much it helped in reality is debatable, if at least it gave a moral boost.
In game it would offer some limited protection (these can be shot off) at the cost of a bit more weight and can save you from a shot or 2 especially badly aimed ones. Furthermore such tracks give the vehicle a more used, fight approved and unique look. Here are some possible looks, tho in game they arent all fixed to historic placements and more can be applied to furhter increase the effect over different survaces.
Here on the StuG IIIs the crew fixed the Engine Deck mushrooms with their roof plate on the front as well as tracks and wooden boards to the side of the hull. Another surviving StuG III Ausf. E also has such and more engine deck plating to the side of the sponsen.
But overall Ostketten and Winterketten can also be used to improve protection over a wider area than normal tracks.
