[Request] Change Enemy Models (for Survival)

[DeathOnWings]

I would like to change the enemy models (russians) in the survival mod to us-soldiers. Mabe also change/edit the audiofiles would be nice, because for the most of non-US-players it would be simply more fun to shoot americans.

I don't care if singleplayer and / or multiplayer does not work correctly after the changes.

Anyone an idea where to search and / or repack?

EDIT 1:
All the audifiles i need are in main/localized * .iwd - files. No i need only the models
