W"Gunwalking", or "letting guns walk", was a tactic used by the Arizona U.S. Attorney's Office and the Arizona Field Office of the United States Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), which ran a series of sting operations between 2006 and 2011 in the Tucson and Phoenix area where the ATF "purposely allowed licensed firearms dealers to sell weapons to illegal straw buyers, hoping to track the guns to Mexican drug cartel leaders and arrest them". These operations were done under the umbrella of Project Gunrunner, a project intended to stem the flow of firearms into Mexico by interdicting straw purchasers and gun traffickers within the United States. The Jacob Chambers Case began in October 2009 and eventually became known in February 2010 as "Operation Fast and Furious" after agents discovered Chambers and the other suspects under investigation belonged to a car club.

WeTrace is an Internet-based firearm trace request submission system, developed by the United States' federal government, Bureau of Alcohol, Tobacco, Firearms and Explosives, that provides for the electronic exchange of traced firearm data in a secure internet-based environment. Participating law enforcement agencies with access to the internet can acquire 24/7 real-time capabilities to electronically submit firearm trace requests, monitor the progress of traces, retrieve completed trace results, and to query firearm trace related data in Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) firearms registration database at the National Tracing Center. Firearms tracing is the systematic tracking of the movement of a firearm from its creation by the manufacturer or its introduction into U.S. commerce by the importer, through the distribution chain to the first retail purchase. Release 4.0, a bilingual version of eTrace was deployed in December, 2009 for the benefit of Spanish-speaking countries.
WReport of Multiple Sale or Other Disposition of Pistols and Revolvers, or ATF Form 3310.4, is a form prescribed by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) for use by firearm dealers holding a Federal Firearms License (FFL) to report when an unlicensed person purchases or acquires two or more handguns at one time or during five consecutive business days.

WThe National Instant Criminal Background Check System (NICS) is a background check system in the United States created by the Brady Handgun Violence Prevention Act of 1993 to prevent firearm sales to people prohibited under the Act. The system was launched by the Federal Bureau of Investigation (FBI) in 1998. Under the system, firearm dealers, manufacturers or importers who hold a Federal Firearms License (FFL) are required to undertake a NICS background check on prospective buyers before transferring a firearm. The NICS is not a gun register, but is a list of persons prohibited from owning or possessing a firearm. The buyer’s details are discarded after the query and a record on NICS of the firearm purchase is not made, though the seller as a FFL holder is required to keep a record of the transaction.
WTitle II weapons, or NFA firearms, are designations of certain weapons under the United States National Firearms Act (NFA).
