Martin was prominent in the development of Fort Indiantown Gap and after his death, the United States Senate renamed the facility the Edward Martin Military Reservation, an honor that Martin himself had rejected throughout his life. The new name was never fully accepted by the military personnel who served there. In 1975, the Secretary of the Army renamed the post Fort Indiantown Gap in order to more closely align it with the other active duty stations throughout the United States. The Joint Force Headquarters of the Pennsylvania National Guard is located at Fort Indiantown Gap, and is named Edward Martin Hall in Martin's honor.
