You shouldn't be using his perks because it's broken.
But I am gonna help you fix the problem.

Copy generic_human to your mod. That can be found in animtrees:
C:Program Files\Steam\steamapps\common\Call of Duty World at War\raw\animtrees

you can add that animation somewhere in body
Build the mod and done.
