The game is starting to get really good in my opinion, but one area where we have seen little development are small things that generate the immersion. To me of those things would be the soldiers uniforms, currently they are in pristine condition, we have soldiers crawling in the mud and their clothes remain parade-worthy when they get up, crawling through barbed wire doesnt tear the clothes, nor does artillery and grenade shrapnell.
Making the clothes ragged doesnt need to be and shouldnt be anything too fancy, it can be similar to War Thunder, where tanks get dusty in a few minutes in the desert.
Walking through barber wire could make the clothes a bit ripped, crawling on the ground or getting shelled would make the snowsuits and summer uniforms dirty, swimming would leave the clothes a bit darker due to being wet.
