What is 0311?
In Marine Corps terms (which, of course, are the only ones that matter...), the MOS for one who is gonna "get some." Not to be messed with. They are the backbone of the Marine Corps, and the reason there is a Marine Corps. If you don't believe me, ask one.
Picture an all powerfull God. With that image, you're getting close... but its hard to describe a Marine in any other way, especially one with the designation 0311.
Rifleman MOS in the Marine Corps Infantry Field. A killer.
"Private Davis, you and the rest of the 0311's pick up your packs and move."
