The 92nd Engineer General Service Regiment was constituted an inactive unit of the Regular Army, effective 1 October 1933, as the 51st Engineer Battalion (Separate). The unit was redesignated on 1 January 1938, as the 92nd Engineer Battalion and activated on 1 May 1941 at
Fort Leonard Wood, Missouri. The enlisted cadre for the 92nd Engineer Battalion was furnished by the 41st Engineer Regiment and numbered 49 men. The unit was manned with Black soliders. The officers were drawn from the Regular Army and members of the
Officers Reserve Corps on active duty. In March 1942, soldiers of Company D assigned to Camp Joseph T, Robinson, Arkansas got into an altercation with white Military and Little Rock policemen. The civilian police shot and killed Sergeant Thomas P Foster who was attempting to investigate a pervious police beating of one of his engineers. A grand jury declined to charge anyone for the killing. The unit was reorganized and redesignated, effective 22 May 1942, as the 92nd Engineer Regiment (General Service). On 1 July 1942, the organization sailed aboard the
USAT Thomas H. Barry from the
New York Port of Embarkation. Landing in Scotland on 13 July, the regiment was assigned to Southern Base Section of SOS, ETOUSA, with station near Taunton, Somerset, in southwestern England. The regiment was the first American unit in that part of Britain. On 1 August 1942, the unit designation was changed to 92nd Engineer General Service Regiment. The regiment sailed from Scotland arriving at Oran, Algeria, in French North Africa on 16 February 1943, and was assigned to the Mediterranean Base Section. In April the unit was attached to the Fifth Army Invasion Training Center in preparation for the Sicily and Salerno operations. From 2 May 1967 through 27 July 1972, the battalion distinguished itself in 14 campaigns: These elements of the 92nd, the only deployed engineer battalion in the Army at that time, built what was to be the U.S. and coalition forces’ initial base camp, staging area and port for debarkation of humanitarian aid to
Afghanistan. Prior to the battalion's arrival, the camps were essentially open fields with few buildings, no electricity, no running water or adequate drainage. At Kandahar,
unexploded ordnance and nightly rocket attacks on the base from enemy forces were common. The runways were cratered from aerial attacks and littered with destroyed aircraft, significantly degrading air operations and presenting a significant threat from unexploded ordnance. There was no waste incineration or sanitary waste-water treatment. All of these issues were corrected. Additionally, the battalion organized and conducted
quarry operations near the airport providing material for rapid runway repair and road building. In January 2005, the battalion deployed to
Baghdad in support of OIF 04-06 to provide general construction engineering and chemical force protection support. 92nd completed 276 construction missions, including the construction of an Iraqi tank gunnery range, a headquarters and airfield complex for the
3rd Armored Cavalry Regiment, numerous battalion and brigade headquarters SEA Huts and the repair of over 100 IED craters.
