H&K UMP

The Heckler & Koch UMP (Universale Maschinenpistole, German for "Universal Submachine Gun") is a submachine gun developed and manufactured by Heckler & Koch. The UMP has been adopted by various agencies such as the U.S. Customs and Border Protection. Heckler & Koch developed the UMP as a lighter and cheaper successor to the MP5, though both remain in production.

There are three variants of the UMP design, chambered in three different cartridges: The UMP features a two-round burst setting. When used, the two-round burst is treated as a Double Tap, granting a +1 to hit and damage and expending two rounds of ammunition.
 * The UMP45, chambered in .45 ACP (shown in the infobox)
 * The UMP40, chambered in .40 S&W (increase Shots to 30)
 * The UMP9, chambered in 9x19mm Parabellum (increase Shots to 30, decrease Damage to 2d6)
