The 37th Engineer Battalion ("Eagle Battalion") was an airborne combat engineer battalion in the United States Army, and a subordinate unit of the 20th Engineer Brigade and XVIII Airborne Corps, based at Fort Bragg, North Carolina. The battalion is notable in that it was the only battalion, of any kind, in the history of the United States Army to have entered combat as both an officially designated amphibious and airborne unit (though the Glider Infantry Regiments of the 11th Airborne Division conducted amphibious assaults in World War II).[citation needed]
