Question: The Steam Wheel Tank was evaluated at which US Army facility?
Context: US Army Garrison Okinawa is a United States Army facility located in Yomitan, Okinawa Prefecture, Japan.  Home to the United States Army on Okinawa, 10th Support Group (Regional), along with the 1st Battalion, 1st Special Forces Group (Airborne), 247th MP DET, and the 349th Signal Company (78th SIG BN) provide support to all other services on island.  Formerly named 'Torii Station', the garrison was re-designated in March 2014. Maj. Gen. Wilfred Charles Menard, Jr. (November 10, 1918 – February 20, 2012) (ARNG) was the twenty-sixth Adjutant General of New Jersey.  Commissioned a US Army 2nd lieutenant in 1942, he served actively with the Army during the Second World War rising to the rank of US Army captain.  He continued to serve thereafter as a reserve officer in the New Jersey Army National Guard, which he commanded from 1974-1982.  A graduate of the United States Army Field Artillery School, the United States Army Tank Destroyer School, and the United States Army War College, Menard was an experienced artillery officer.  During his service with the Guard, he was briefly reactivated at the rank of Lieutenant Colonel for the Berlin Crisis of 1961.  Born in Trenton, NJ, Maj. Gen. Menard was a lifelong resident of central New Jersey.  His many military awards and decorations include the Distinguished Service Medal (US Army) and the Legion of Merit. Besides the US Army wartime publication, there is no evidence this "light tank" or tankette existed.  What is claimed in the US Army wartime publication to be the Type 93, is actually a later version of the Type 92 cavalry tank (tankette). The 416th Theater Engineer Command (TEC) is a United States Army Reserve unit that conducts theater-level engineer operations for US Army Central Command, US Army Southern Command, supports continental U.S. – based engineer requirements as directed, and is prepared to participate in Joint and Combined regional contingency operations.  It is also the higher command headquarters for the US Army Facility Engineer Group. Haebangchon (Hangul: 해방촌 Hanja: 解放村) (Haebang - meaning: freedom or liberation, and Chon - meaning: village) is a district of Yongsan-gu, in Seoul, South Korea.  It is one of the oldest neighborhoods in central Seoul, today.  It is also known as the neighborhood at the foot of Namsan (남산자락).  The neighborhood's close proximity to Itaewon and the Yongsan Garrison US Army facility has made the area popular for expatriates and for military residents.  In recent years, the area has become a haven for people from a variety of English speaking nations.  The neighborhood is home to Korean residents, as well as Americans, Canadians, Filipinos, Australians, New Zealanders, Britons, Nigerians, and Russians, who have found their home in the "Freedom Village".  Many businesses in HBC are foreign-owned and offer a distinct flavor not found elsewhere in Seoul. The Tooele Chemical Agent Disposal Facility (also called Tooele Chemical Demilitarization Facility) or TOCDF, is a U.S. Army facility located at Deseret Chemical Depot in Tooele County, Utah that was used for dismantling chemical weapons. Destruction is a requirement under the Chemical Weapons Convention and is monitored by the Organisation for the Prohibition of Chemical Weapons.  Deseret Chemical Depot held 44% of the nation's chemical stockpile when processing began, and it had held some of these chemical munitions since 1942.  TOCDF was constructed in the early 1990s and began destruction of chemical agent-filled munitions on 22 August 1996.  As of September 2011, the facility had processed 99% of its stockpile.  TOCDF processed all of its VX, Sarin and mustard gas at its main facility; a smaller incinerator was installed west of the main plant in order to dispose of Lewisite-filled containers.  In advance of plant closing, two ponds were revitalized and the surrounded area reseeded as well as 29 miles of railroad being removed (out of 40-miles of rail in Deseret).  Disposal of all chemical weapons concluded on 21 January 2012.  It was the last depot to complete its disposal operations under the U.S. Army Chemical Materials Agency; although two other depots still store chemical weapons to be destroyed by the Assembled Chemical Weapons Alternatives program at Pueblo, Colorado and Bluegrass, Kentucky. The Steam Wheel Tank was a U.S.-produced, prototype armoured fighting vehicle built by the Holt Manufacturing Company (now Caterpillar Inc.).  Developed sometime between late 1916 and early 1917, it was the third tank to be designed in the U.S.  The prototype was completed in February 1918 and was evaluated between March and May 1918 at Aberdeen Proving Ground.  It performed poorly and was not developed further. SM-1 was a 2-megawatt nuclear reactor developed by the United States Atomic Energy Commission for the US Army Nuclear Power Program (ANPP) in the mid-1950s.  The compact "package" reactor was designed to produce electricity and generate heat for remote military facilities.  The first, the SM-1, served as the Army's primary training facility to train reactor operations personnel from all three services (Army, Navy and Air Force).  In 1954, the Department of Defense placed the US Army in charge of all military nuclear power plants except those used for propulsion by the US Navy.  The Army's Chief of Engineers established the US Army Engineer Reactors Group in April 1954, and decided to construct the SM-1 facility at the Corps of Engineers headquarters at Fort Belvoir, Virginia, about 18 miles south of Washington, D.C..  About 800 personnel were trained on the SM-1 during its operational life, from 1957 to 1973.  The power plant was shut down in March 1973, and is monitored within a "restricted access" section of the post.  Inspectors enter the shut-down operations control room every decade or so, and the building may be demolished "about 50 years" after the reactor core was removed, possibly around 2030. Aberdeen Proving Ground (APG) (sometimes erroneously called Aberdeen Proving "Grounds") is a United States Army facility located adjacent to Aberdeen, Maryland (in Harford County).  Part of the facility is a census-designated place (CDP), which had a population of 3,116 at the 2000 census, and 2,093 at the 2010 census. Erie Proving Ground was a former United States Army facility.  Originally a camp to train gunners, the facility's foundation was due to the Spanish–American War's lack of skilled riflemen.  The facility was located in Ottawa County, Ohio.  The facility was established in 1918 originally as Camp Perry Proving Ground.  The facility was at various times named Erie Ordnance Depot and Erie Army Depot.  During World War II over 5,000 people ended up being employed there.  The employed people were testing various weapon systems, armor, and such during World War II.  During peacetime it served as a storage, maintenance, and repair facility.  Erie Proving Ground closed in January 1967.
