Right now I'm in the process of making a Wild West mod, so I just created my first unit for it; a western Ranger. He is based on the Rifleman, and uses said animations. I really like how this one turned out, and it should be the first of many new Western units.
Update 10/21/09: This unit has been broken for a while, but I've just got the fix added.
