Bureau of Alcohol, Drugs, Tobacco, Firearms, and Lasers

The Bureau of Alcohol, Drugs, Tobacco, Firearms and Lasers was a specialized federal law enforcement and regulatory organization in the United States before the Great War. Among other things, BADTFL offices were responsible for issuing special permits for the civilian use of combat armor, because this kind of equipment was designated for military and police use. It also issued firearms licenses and conducted firearms licensee qualification and compliance inspections.

In the 21st century, 10mm was the standard ammunition caliber of the BADTFL, used in 10mm pistols and 10mm SMGs, whereas the military was primarily concerned with energy weapons.
