The 6th Machine Gun Battalion was a battalion of the United States Marine Corps which served during World War I. Along with the 5th and 6th Marine Regiments, the battalion was part of the 4th Marine Brigade. After being formed in 1917, the battalion supported the Marine regiments by detaching machine gun companies to operate with the regimental battalions along the Western Front and to provide fire support to them during the fighting. In addition to this role, the battalion was sometimes employed as a complete unit with all its companies being concentrated together to ensure that maximum firepower was applied to various points along the front line in support of Allied attacks and also to defend against German assaults. The battalion also supported the operations of the 2nd Infantry Division. After the war, the unit undertook occupation duties in Germany before returning to the United States in mid-1919 where it was subsequently deactivated.
