Question: Lieutenant General Winston Mensa-Wood's position from 1987 to 1990 is currently held by what Major General?
Context: At the Battle of Brandywine on September 11, 1777 a colonial American army led by General George Washington fought a British-Hessian army commanded by General William Howe, 5th Viscount Howe.  Washington drew up his troops in a defensive position behind Brandywine Creek.  Howe sent Lieutenant General Wilhelm von Knyphausen's 5,000 troops to demonstrate against the American front at Chadd's Ford.  Meanwhile, Lieutenant General Charles Cornwallis took 10,000 troops on a wide flank march that crossed the creek and got in the rear of the American right wing under Major General John Sullivan.  The Americans changed front but Howe's attack broke through. The head of the Ghana Army was formerly referred to as the army commander but now has the title above.  The list of former heads lies below.  The current Chief of Army Staff is Major General William Ayamdo.  He was appointed to the position by President Akuffo-Addo on 9 February 2017. The Battle of Wittstock took place during the Thirty Years' War (1618-1648).  It was fought on 24 September (Julian calendar) or 4 October (Gregorian calendar) 1636.  A Swedish-allied army under general commanded jointly by Johan Banér and Alexander Leslie, later 1st Earl of Leven decisively defeated a combined Imperial-Saxon army, led by Count Melchior von Hatzfeld and the Saxon Elector John George I.  Leslie and Banér commanded two distinct armies: Banér commanded the Swedish main army (huvudarmén), and Leslie commanded the Army of the Weser.  Their subordinate officers included the Swedish Count and major General Lennart Torstenson, Lieutenant General James King (later first Lord Eythin), and Major General John Ruthven who is usually erroneously conflated with his uncle Patrick Ruthven who was also a Lieutenant General in the Swedish army, but not present at Wittstock. Lieutenant General Winston Mensa-Wood is a retired Ghanaian military officer and served as the twenty-third Chief of Defence Staff of the Ghana Armed Forces from June 1990 to March 1992.  He took over from Lieutenant General Arnold Quainoo and handed over to Air Marshal Achilles Harry Kwami Dumashie.  Prior to that, he was Chief of Army Staff from 1987 to 1990. In the United States Army, United States Marine Corps, and the United States Air Force, lieutenant general (abbreviated LTG in the Army, Lt Gen in the Air Force, and LtGen in the Marine Corps) is a three-star general officer rank, with the pay grade of O-9.  Lieutenant general ranks above major general and below general.  Lieutenant general is equivalent to the rank of vice admiral in the other uniformed services. Major general (short MG or Maj. Gen.) is a military rank used in many countries.  It is derived from the older rank of sergeant major general.  The disappearance of the "sergeant" in the title explains the apparently confusing phenomenon whereby a lieutenant general outranks a major general (although a major outranks a lieutenant, a lieutenant outranks a sergeant-major.) In the United States Army, United States Marine Corps, and United States Air Force, major general is a two-star general-officer rank, with the pay grade of O-8.  Major general ranks above brigadier general and below lieutenant general.  A major general typically commands division-sized units of 10,000 to 15,000 soldiers.  Major general is equivalent to the two-star rank of rear admiral in the United States Navy and United States Coast Guard and is the highest permanent rank during peacetime in the uniformed services.  (The higher ranks are temporary ranks linked to specific positions, although virtually all officers who have been promoted to those ranks are approved to retire at their highest earned rank.) Nadja Y. West (born 1961) is a United States Army lieutenant general and the 44th U.S. Army Surgeon General and Commanding General of the U.S. Army Medical Command.  West is the first black Army Surgeon General, and was the first black female, active-duty, major general and the first black female major general in Army Medicine.  West is also the first Army black female lieutenant general.  She is the highest ranking female to have graduated from the United States Military Academy.  She received the Army Distinguished Service Medal, the Defense Superior Service Medal, the Legion of Merit, and others. Lieutenant General Arnold Quainoo is a retired Ghanaian military officer and served as the Chief of Defence Staff of the Ghana Armed Forces from August 1983 to September 1989.  He took over from Flight Lieutenant J. J. Rawlings and handed over to Lieutenant General Winston Mensa-Wood.  He was also the first commander of the Economic Community of West African States Monitoring Group (ECOMOG) which intervened in Liberia to help end the civil war.  He also served twice as Army Commander, first in 1979 following the coup-d'état by the Armed Forces Revolutionary Council which overthrew the Supreme Military Council.  He was replaced when the Limann government was elected.  He was however re-appointed as Chief of Army Staff following the coup by the Provisional National Defence Council and later as General Officer Commanding the Ghana Armed Forces. Lieutenant General Rhett A. Hernandez is a retired officer in the United States Army and the former commander of the United States Army Cyber Command which is the Army’s service component to U.S. Cyber Command.  Hernandez, as a major general, assumed the position upon its activation (which included the command receiving and perpetuating the lineage and honors of the former Second United States Army) on October 10, 2010, with its headquarters at Fort Belvoir Virginia.  He received a promotion to lieutenant general on March 25, 2011.  As head of US Army Cyber Command, Hernandez was responsible for planning, coordinating, and integrating the network operations and defense of all US Army networks.  Hernandez also was tasked with conducting cyberspace operations in support of Army operations through his command of approximately 21,000 soldiers and civilians.  Hernandez oversaw a command that brought an unprecedented unity of effort and synchronization of all Army forces operating within the cyber domain.  Under Hernandez, the command concentrated its efforts on operationalizing cyberspace and improving Army capabilities in the cyberspace domain.  As a first step, the command established the Army Cyber Operations and Integration Center collocating intelligence, operations, and signal staffs, together with a critical targeting function, and bringing a new synergy to Army cyberspace operations.  To improve the Army’s cyber capabilities the command fielded a World Class Cyber Opposing Force at the National Training Center; developed new doctrinal concepts for Land-Cyber operations; and identified the Army’s capability requirements needed to fully operationalize the cyberspace domain and grow the Army’s cyber force.  He currently serves on the Board of Advisors of the Military Cyber Professionals Association (MCPA).
