|The following is based on Van Buren and has not been confirmed by canon sources.|
The Unamerican Activities Force (UAF) was a pre-War organization consisting of federal, undercover agents that worked to ferret out communist sympathizers in the American population. They wore the stealth UAF armor. 
The UAF have not appeared in, nor are they ever mentioned in any currently published or canonized game(s). Lore detailing, and items remaining from their pre-War existence were supposed to have appeared in Van Buren, the canceled Fallout 3 by Black Isle Studios.
