The MP5 is one of the most widely used submachine guns in the world,[10] having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations.[11] It was widely used by SWAT teams in North America, but has since been supplanted by M16 variants in the 21st century.

In 1999, Heckler & Koch developed the UMP, the MP5's successor.[12] Despite its higher cost, the MP5 remained the more successful of the two options.[13]
