Is there a way to install this but keep the 95th rifles instead of the 60th?
Yes, thanks to the new mod layout. Install the mod as usual, then head over to your NW module folder and open up "module.ini". Use the find function to search for "custom" and it'll take you to the section that lists all the customisable units.
Remove the # from infront of the unit you want, and add the # infront of the unit that's currently there. All units have been named so it's easy to see what you're replacing/removing.
Not only can you do this for uniforms, but also for animations!
Once you've done that and saved the file, head over to the rar archive that has the troops.txt files in and extract the file for the troop you just added to the game. Rename it "troops.txt" and let it replace the one that's currently there.
Enjoy!
