This client side IWD removes the guns from swaying when you're standing still and aiming down the sight. This removes the documented sway bug; that shots are not registered in the middle of the crosshair or the middle of the screen, they just register randomly.
If you want proof of the bug and discussions: http://www.infinityward.com/community/forum/index.php?topic=10703.0

All weapons except the snipers are added here, this is because to fix the snipers the easy way, they would become "CS-snipers", meaning you wouldn't have to hold your breath to hit. I have not yet found a way to make the snipers "COD2-snipers", meaning when you're holding your breath the crosshair is not moving, but moving otherwise.

This .iwd should work with all mods, just place it in the same folder as the mod you want to use. Because it is a client side IWD, people will have to be able to download it from the server, if they don't have it already.
