which branch of the service was once known as the revenue marine
United States Revenue Cutter Service The United States Revenue Cutter Service was established by an act of Congress (1 Stat. 175) on 4 August 1790 as the Revenue-Marine upon the recommendation of Secretary of the Treasury Alexander Hamilton to serve as an armed customs enforcement service. As time passed, the service gradually gained missions either voluntarily or by legislation, including those of a military nature. It was generally referred to as the Revenue-Marine until July 1894, when it was officially renamed the Revenue Cutter Service.
United States Marine Corps The Marine Corps has been a component of the U.S. Department of the Navy since 30 June 1834,[13] working closely with naval forces. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers.[14]
