(CAR-15A3 Model 927) and 40×46mmSR Colt M203A1 underbarrel grenade launchers.
The standard CIA weapons used to be the 9×19mm FN-Browning HP-35 pistol and 18.5×70mmR Winchester Model 1200 Defender pump-action shotgun, but these have certainly been replaced by more recent
designs.
The CIA's own Cessna U-27A (Model 208B Caravan I) Utility/Special Missions Aircraft can be used to deliver seven men by parachute.

These agents carry 9×19mm SIG-Sauer P228 pistols, 9×19mm H&K MP5K-PDW submachine guns, 9×19mm H&K MP5A5N submachine guns, 5.56×45mm H&K HK53A5N assault carbines (main longarm), 7.62×51mm
H&K G3K battle rifles and shotguns.
Drug Enforcement Agency (DEA)
The DEA initially issued various revolvers to its agents, however, from 1987, agents could field one of the following pistols: 9×19mm Beretta Model 92F, 9×19mm Glock 17, 9×19mm SIG-Sauer P226 or 9×19mm S&W
Model 459. Between 1992 and 1998, the standard issue sidearm was the 9×19mm SIG-Sauer P228 pistol, replacing the earlier weapons. In late 1998, the 10×21mm (.40 S&W) Glock 22 and 23 pistols were adopted
as new standard handguns. However, since 2000, after graduating from basic training, agents can replace the Glock with the 10×21mm (.40 S&W) H&K USP Compact, 10×21mm (.40 S&W) SIG-Sauer P226,
10×21mm (.40 S&W) SIG-Sauer P229 or 10×21mm (.40 S&W) SIG-Sauer SP2340, if they want - these are acquired through the agency. The H&K USP Compact seems to be the most popular. Other guns available
include the 9×19mm Colt CAR-15 Model 633 submachine gun, 9×19mm Colt CAR-15 Model 635 submachine gun (at least 2,200 bought since 1988), 10×21mm (.40 S&W) H&K UMP submachine gun (3,000 replacing
the CAR-15 weapons beginning in 2001), 5.56×45mm Colt CAR-15A2 Model 720 burst-fire carbine (M4), 5.56×45mm H&K HK53A5N assault carbine (main rifle calibre weapon), 5.56×45mm Colt AR-15A2 Model 645
burst-fire rifle (M16A2), 5.56×45mm Colt HBAR-15A2 Model 750 light machine gun, 7.62×51mm Saco M60 machine gun, 18.5×70mmR Remington Model 870P pump-action shotgun (with 14" barrel) and 40×46mmSR
Colt M79 grenade launcher. The heavy weapons are, of course, not normally used in the USA, but rather during drug war operations in South and Central America.
Helicopters include the Bell UH-1H Iroquois and the newer Sikorsky UH-60A Black Hawk, both with two door-mounted 7.62×51mm Saco M60D machine guns when used against drug smugglers.
Federal Sky Marshals
Issue sidearm is the 9×19mm SIG-Sauer P228 since 1992.
Federal Bureau of Investigation (FBI)
The FBI issued 9×29mmR (.38 Special) Colt Official Police and 9×29mmR (.38 Special) S&W Model 13 Military & Police revolvers in the 1980s. Authorised privately-purchased weapons included the 9×33mmR (.357
Magnum) S&W Model 19 Combat Magnum revolver and 11.43×23mm (.45 ACP) SIG-Sauer P220-1 pistol. This situation was finally seen as no longer adequate, and some 1,500 9×19mm SIG-Sauer P226 and 1,000
9×19mm S&W Model 5946 pistols were purchased in 1988, which most field agents never got, however. In 1991, the Bureau received at least 9,500 copies of the 10×25mm S&W Model 1076, which was especially
designed for the FBI (as seen in "Twin Peaks"). It was issued with four 9-round magazines, two 11-round magazines and one 15-round magazine per agent. However, the gun turned out to be a complete failure. All
were returned to the factory. Thus, some 15,000 9×19mm SIG-Sauer pistols were purchased over the course of the 1990s, most of them P226s. In 1993, the more compact 9×19mm SIG-Sauer P228 was adopted.
Agents with very small hands, especially women, could opt for the slimline 9×19mm SIG-Sauer P225. Since January 1998, all new agents are trained on the 10×21mm (.40 S&W) Glock 22 pistol, with the smaller
10×21mm (.40 S&W) Glock 23 for those who prefer it. The ultra-compact 10×21mm (.40 S&W) Glock 27 is authorised as concealed backup. Older agents continue to field their SIG-Sauer pistols, if they wish, and
even new agents can switch to the 9×19mm guns if they qualify with them. Several small revolvers are authorised for undercover agents, including the 9×29mmR (.38 Special) S&W Model 10 Military & Police
(with 2" barrel), 9×29mmR (.38 Special) S&W Model 38 Bodyguard Airweight (with 2" barrel), 9×29mmR (.38 Special) S&W Model 60 Chief's Special Stainless (with 2" barrel) and 9×33mmR (.357 Magnum) S&W
Model 19 Combat Magnum (with 2.5" barrel).
Since 1989, the FBI issued the 9×19mm H&K MP5SFA2 (and MP5SFA3) semi-automatic carbine to field agents. These are identical to the MP5A4 and MP5A5 submachine guns respectively, except for the fact that
they are only capable of single shots. Beginning in 1994, they were replaced by the 10×25mm H&K MP5/10A2 submachine gun (offering single shots and 2-round bursts only). In rural areas, semi-automatic
5.56×45mm carbines and rifles such as the Colt CAR-15A2 Model 6520 are used. Only SWAT-qualified agents can field full-automatic weapons. The standard shotgun is the 18.5×70mmR SGT Tactical Response
Model 90102 FBI, a modified Remington Model 870 with tactical light and spare rounds holder.

Regional SWAT
These agents are trained by the HRT, and similarly equipped. They used the 9×19mm SIG-Sauer P226 until 1998, when some 5,000 11.43×23mm (.45 ACP) Springfield Bureau Model pistols were purchased, a
heavily customised Colt M1911A1-clone. They also have 9×19mm H&K MP5A2, MP5A3 and MP5SD3 submachine guns, 10×25mm H&K MP5/10A3 submachine guns (with 2-round burst setting), 5.56×45mm Colt CAR-
15A2 Model 777 assault carbines (since about 1998), 5.56×45mm Colt AR-15A2 Model 645 burst-fire rifles (M16A2), 7.62×51mm H&K G3A3 battle rifles (especially for use in rural areas), 7.62×51mm Remington
Model 700 bolt-action sniper rifles (M40A1 configuration with 10× scope), 12.7×99mm McMillan Model 87 bolt-action sniper rifles and 18.5×70mmR SGT Tactical Response Model 90102 FBI pump-action shotguns.
(The arsenals of many SACs often also contain less orthodox weapons, such as 11.43×23mm (.45 ACP) Auto-Ordnance M1928 Tommy Guns and 40×46mmSR Colt M79 grenade launchers. But these are not normally
used.)
Vehicles in service include the Cadillac Cage Peacekeeper 4×4 armoured car, DDGMC LAV-APC Bison 8×8 armoured personnel carrier and the Sikorsky UH-60A Black Hawk helicopter.

Hostage Rescue Team (HRT)
When the HRT was founded in 1983, it first used the 9×19mm FN-Browning HP Mk 2 pistol, which was later supplemented by the 9×19mm SIG-Sauer P226 pistol. In 1995, 250 11.43×23mm (.45 ACP) Les Baer SRP
Bureau pistols built on a high-capacity Para-Ordnance frame were acquired. The HRT also uses the 9×19mm H&K MP5SD6 suppressed submachine gun, 10×25mm H&K MP5/10A3 submachine gun (adopted 1994),
5.56×45mm Colt CAR-15A2 Model 777 assault carbine, 5.56×45mm Colt AR-15A2 Model 645 burst-fire rifle (M16A2), 5.56×45mm H&K HK33A2 assault rifle, 7.62×51mm H&K PSG1 sniper rifles (with 6× scope),
