Can someone modify the current nazi model to add grenades to the player model?

EXAMPLE: http://easycodod.honortolkien.org/german_poster.jpg

Also can someone possibly make it so the sleeves are rolled up to the elbow like the picture above? I don't know if this part is with the model or what part of the .vtf file to change it.

that would need the 3D Model to be changed.. :{

and that is exactly what he's asking for.
