The Continental Marines were the Marine Force of the Colonies during the Revolutionary War. The Corps was formed by the Continental Congress on November 10, 1775 and was disbanded in 1783. Their mission was multi-purpose, but their most important duty was to serve as on-board security forces, protecting the Captain of a ship and his officers. During naval engagements Marine sharpshooters were stationed in the fighting tops of the ships' masts, and were supposed to shoot the opponent's officers, naval gunners, and helmsmen.
