Hunzeker was born in
Pittsburgh, Pennsylvania, on August 26, 1952. He entered the USMA in July 1971 from the
USMA Preparatory School in
Fort Belvoir, Virginia, as an enlisted soldier. He graduated West Point as a
second lieutenant in the
Field Artillery branch in 1975 and served as a
forward observer, a fire direction officer, a
battery executive officer and a brigade fire support officer. Following attendance at the Field Artillery Advanced Course at Fort Sill, he commanded at the battery level and also served as a battalion operations officer. Hunzeker commanded a field artillery battalion at Fort Sill, Oklahoma, followed by a posting as divisional artillery commander in charge of a brigade-sized artillery element in Germany. Hunzeker served in the Army Personnel Command as an operations research systems analyst from 1985 to 1988. He was later assigned to the Army's Program Analysis and Evaluation directorate (2001), and in 2003 as the vice director of the Joint Staff agency responsible for Force Structure development (J-8). While there, he oversaw the return of the division back to Fort Riley, Kansas, its longtime home. After a year in command of the division, Hunzeker became commanding officer for the
Operation Iraqi Freedom Civilian Police Assistance Training team in Iraq, which provided oversight and guidance for more than 400,000 Iraqi police force personnel throughout the country. In his final two assignments and after being promoted to
lieutenant general in 2007, Hunzeker first commanded the
U.S. Fifth Corps in Germany, and then served as the deputy commander of all U.S. forces in Iraq – the position he held when he retired. ==Post-military employment==
