The Paramarines (also known as Marine paratroopers) was a short-lived specialized combat unit of the United States Marine Corps, trained to be dropped from planes by parachute. Marine parachute training which began in New Jersey in October 1940 ended with the parachute units being disbanded at Camp Pendleton, California in February 1944. Paratroopers received a significantly increased salary after completing training, so there was no shortage of volunteers, although all were required to be unmarried. Standards of fitness were high, and 40% failed the training course.
The first cohort of Marines paratroopers trained at NAS Lakehurst in New Jersey in October 1940, eventually becoming the 1st Marine Parachute Battalion. They were followed by a second group in December 1940, forming the 2nd Marine Parachute Battalion. A third class trained at Camp Kearny in San Diego, California in early 1941, eventually forming the 3rd Marine Parachute Battalion. After the United States entered World War II, the training program was stepped up, and a special training camp and parachute training school was opened temporarily at Camp Elliott in San Diego in May 1942, next to Camp Kearny, moving to purpose-built accommodation nearby at Camp Gillespie in September 1942. A second training camp and parachute training school opened at Hadnot Point on the New River in North Carolina in June 1942, but closed in July 1943.
