The Delaware State Guard is the currently inactive state defense force of the state of Delaware, which was active during both World War I and World War II. As the official militia of the state, the Delaware State Guard was created with the intent of acting as a stateside replacement for the Delaware National Guard while the National Guard units were deployed abroad.
