Fort Rucker, or Camp Rucker, is a former United States Army post in Cochise County, Arizona. First known as Camp Supply and Camp Powers, its name was changed on October 1, 1878 in honor of Lieutenant John Anthony "Tony" Rucker. On July 11, 1878, Lieutenant Rucker died in an unsuccessful attempt to save the life of a fellow soldier, Lieutenant Austin Henley, when the two tried to cross a nearby river which had swelled following a rainstorm.
