Marine Corps Weapon Systems: MK19
The MK19, also known as the "Mark 19," is a highly effective weapon when effective suppressive fire support is needed. It is capable of wiping out light armored vehicles and protecting supply convoys. The MK19 provides Marine infantry battalions with the means to deliver massive direct fire or indirect fire from hidden positions. The MK19 rapidly fires explosive 40mm grenades, making it an ideal weapon against enemy armored, mechanized, and infantry forces. Marines become familiar with this while attending SOI.
