Before the Great War took place, Weber was a corporal and part of the United States Army ranger unit Taggerdy's Thunder. After the war took place, he remained with the rest of the Thunder and formed the Appalachian chapter of the Brotherhood of Steel, being given the rank of squire. Weber was a talented salvager and recovered numerous items, including a military security system later installed at Fort Defiance. Weber disappeared while out on patrol after the operation, presumed dead by the few group members that survived him.
Gary Weber is mentioned only in Fallout 76.
