0331 

An 0331 is Marine machine gunner. the dumbass above failed to mention that its not just a SAW they carry. They also employ the M240B, M2 .50 cal, and the MK-19 40mm machine gun. They are the most badass muthafuckas to walk this earth and are the backbone of Marine Infantry units.

0331's are the badasses of America's most badass fighting force
