Not sure if a post has already been made on this topic but I will give it a try.
I believe that it will give the game a much deeper sence of war if we get a greater damage model. If we take a look at the M&B damage for exampel, well you get red and fall over thats it. We should get way more detailed damage, entry and exile hole for the bullet. And if you take a cannonball to the face? Well your damn head is gone mate. It would add a ton to the game if we had a greater damage model with amputations, and it would make the game 100 times more realistic
