Mk19

The Mk 19 40mm Grenade Launcher (commonly just known as "Mk 19") is a belt fed, blowback operated, air cooled, crew served, fully automatic grenade launcher. It fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 is able to launch its grenade at a maximum distance of 2,212 meters, though its effective range for a point target is about 1,500 meters, since the large rear leaf sight is only graduated to 1,500 meters. It is notabley seen as one of the primary weapons used in the arsenal of the AAV-7A1 AMTRAC.

Singe Player
The Mk 19 appears in the mission Thunder Run on the turret of a AAV-7A1 AMTRAC, dropping off marines as M1A2 Abrams tanks move through the PLR artillery camp, as well as in Rock and a Hard Place, again on the turret of a AAV-7A1 AMTRAC.

Multi Player
In Multiplayer mode, the Mk 19 is used by the AAV-7A1 AMTRAC on Kharg Island, Tehran Highway in Rush and Noshahr Canals and Wake Island in the Conquest and Rush game modes.

The Mk 19 is used with a .50 Caliber M2 HMG by the gunner of the AAV-7A1 AMTRAC, the Mk 19 is very good at suppressing enemy infantry and destroying enemy buildings and infastructures while the M2 HMG is often used to kill infantry at close range. The Mk 19 has little effect against vehicles like the T-90A but is effective against lightly armoured vehicles and jeeps.
