Alright thank you, I'll see what other CoD5 models work before trying CoD4.

No cod 5 arms are going to work without an ads joint. Which none of them have. CoD4 animations animate the tag_ads joint but in cod 5 the animations animate the torso. You might be able to change the order of the joint hierarchy in maya to get cod 5 arms to work but I would suggest just going to straight to cod 4 to save yourself some time.

Thanks for clarifying that, I'll see what I can do.
