Changing attributes materials to Captain & Chief

Hello
I'm looking forward changing the Weapon axe by rifle used by both Captain and Super Chief of the Apachean tribe ....so instead they could both shoot as primary weapon and use the axe as secondary weapon exactely such as the "gunners"
Can you give me a link where to get an idea on How modding the attribute of the both General & Captain .
I guess that if I import (merge) the rifle with Milkshape and remap it with Photoshop it won't be enough to work , because something more need to be changed in the attribute:inquisitive: but I don't know where to find how to make the model "understand" it's new weapon ....new in modding :idea2:

thanks

I don't think you can change the actual Captain/General's models and its actions though. Only their bodyguard unit's.

Yes , I know how to chang the faction Bodyguard, but I want to try to Mod the Captain ....or General , ; Maybe it can't be done .
BTW Thanks for answering
