Military Duties:

Machine gunners will spend a large portion of their Marine Corps career at the armory. Clean and well-maintained weapons are extremely important, so it is not uncommon for 0331 marines to spend several hours per day at the armory where they will be cleaning and maintaining their weapons. In addition to armory time, machine gunners will also spend a significant amount of time in the field. Training is best when it is most realistic, so infantry battalions will find ways to make sure that all 0331’s are most prepared for war. This is done by sending infantry platoons into the field for days or weeks at a time where they will practice “humping” (hiking), deploying weapon systems, and trenching in to fighting positions.
