The MP5 (German: Maschinenpistole 5; English: Machine Pistol Model 5) is a 9×19mm Parabellum submachine gun produced by German arms manufacturer Heckler & Koch. It was first developed in 1964, and has since been adopted by many police and military agencies worldwide. The weapon is featured in several games of the Ryanverse.
The preferred submachine gun of counter-terrorist operatives around the world, Heckler & Koch's MP5 is known for its reliability and accuracy, even when firing on full automatic. RAINBOW uses the 9mm MP5A2 fitted with single, triple, and full-auto trigger group.
