Ruger MP9

The Ruger MP9 is a machine pistol used by the USMC in Danger Close: Art of War, the gun is usable in Campaign and in Multiplayer and it's only seen in the US campaign.

Overview
Built in the 1980's, the Ruger MP9 is a variant of the Uzi, which was also designed by the MP9's designer, Uziel Gal. The MP9 hasn't seen widespread use in the US Military like the M4A1 or M9 have, but it's still quite popular among police forces in the USA.

In Singleplayer this weapon is only available in the following levels: Red Devil, Strike at Fallujah and Burning City. The player, Sam Fordson, uses in on Burning City as a starting weapon.

It is unlocked on Multiplayer at level 4, along with the Machine Pistol class. The Ruger MP9 is quite popular amongst low ranks because of its high fire rate and moderate recoil.
