The MP5 (short for Maschinenpistole 5) is a submachine gun produced in 1964 by the West German company Heckler & Koch GmbH. It is probably one of the most commonly used submachine guns in the entire world and is favored by not only foreign military forces, but by US civilian authorities (most notably, S.W.A.T. and the FBI's Special Tactics Unit). It uses standard 9mm Parabellum rounds, which are interchangeable with a number of other machine guns and pistols. All variants of the MP5 have a removable or collapsible stock (depending on when it was produced), though the HK-5 predominantly has a removable stock. All variants are also capable of accommodating a screw-on silencer; but the flash suppressor must be removed.


Though the MP5 has many variants, for the purposes of this article only the MP5K or HK-5 will be mentioned here. The HK-5 is smaller, lighter, and is, thus, more easily concealable. It, like the MP5 has an optional (or telescoping) stock, but is preferably used without it, making it not much larger than a .50 Desert Eagle Mark XIX (and is actually smaller than than the Mark XIX with a 10 in. barrel). Without the stock, the HK-5 is usually called a machine pistol. This variant, while used by many military organizations around the world (including SOCOM, and many anti-terrorism units), is more commonly used by terrorists or gang members due to its smaller size and weight. Besides the above-mentioned differences, and the addition of a secondary hand-grip, it is exactly the same gun as the MP5 (though with a higher rate of fire).

Terminator Franchise

The MP5A3 is used throughout the Terminator franchise as the standard submachine gun. In Terminator: The Sarah Connor Chronicles, the Nightmare Terminator used twin MP5s in Terminator: The Sarah Connor Chronicles pilot episode during his shootout with the police. The MP5 is used by FBI S.T.U. agents during the assault on Cromartie in "What He Beheld" and by both Sarah Connor and Derek Reese in "Mr. Ferguson is Ill Today" during the demise of Cromartie in Mexico. Cromartie himself wielded an HK-5 in his left hand (with a Glock 17 in the other) in his defense.

In Terminator 2: Judgment Day the SWAT teams in the Cyberdyne Systems building used the MP5, while the T-1000 use the HK-5.

The T-800 Endoskeleton is also known to use the MP5 on the battlefield (see the associated article), and it is commonly used by both Resistance fighters and various Terminators in the Comic Book franchises.

Sarah used an MP5K to shoot the barrels with corrosive material so that the T-1000 could be destroyed.
