I had the pleasure of creating this character model when I was working as lead character artist at elite3d for Call of Duty WWII Nazi Zombies. I was responsible for creating the high, low poly, bakes and textures. Face and hair done by Sledgehammer games.
It was a great team effort with my colleague Jose Cifuentes, he did the high poly, low poly, textures from legs, boots and backpack. You can see his work here:
