Gadna (Hebrew: גדנ״ע) is an Israeli military program that prepares young people for military service in the Israel Defense Forces. It was established before the foundation of the State of Israel and was anchored in law in 1949. Today it is a one-week program of discipline and military training usually under commanders serving with the Nahal infantry brigade. Gadna hosts an estimated 19,000 Israeli youth annually, as well as numerous foreign youths.[1]
