The H&K MP5 is the most iconic and widely deployed submachine gun of the modern era, used by special operations forces, hostage rescue units, and police worldwide. Based on the G3 roller-delayed action scaled down to 9mm, it offers exceptional accuracy at submachine gun ranges. The global broadcast of the SAS's Iranian Embassy siege in 1980, where black-clad operators carried MP5s, made it the defining image of counter-terrorism for a generation.
