What is "paramarines"

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.
