The 37th Engineer Battalion ("Eagle Battalion") is an airborne engineer battalion in the United States Army, and currently subordinate to the 2d Brigade Combat Team, 82d Airborne Division, based at Fort Bragg, North Carolina.  The 37th Engineer Battalion was reactivated in the 82d Airborne Division as part of the United States Army new BCT 2020 concept in which each BCT's Special Troops Battalions would be inactivated and reactivated as Brigade Engineer Battalions.  Prior to this, the battalion was a subordinate unit of the 20th Engineer Brigade assigned to XVIII Airborne Corps.
 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]
 The 37th Engineer Battalion was first activated on 16 January 1918, as 1st Battalion, 37th Engineer Regiment, whose primary function was electrical and mechanical engineering. During World War I, the battalion participated in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive as a member of the American Expeditionary Force.
