Modding a Mod

[jedidavebo]

Hello all!
I have been checking out some of these cool mods and was wondering if there is a way to edit someone else's mod.  Lets say you want to use a particular weapon or character out of the mod to learn and use on your own, with permission.  How does one go about that?

I tried using BFBuilderPro  but i don't know where to place the modded files so that bfbuilder will find them and extract them. 

Thank you for any help once again!

[EDIT]: I looked around and i don't think you can except for textures.

Yes, you usually need the assets for the mod.

There are some limited things you can do with hex editing though, such as changing reinforcement counts, etc.
