"The Global Security Environment & Challenges Facing the U.S. Army"
General George Casey became Chief of Staff of the Army on April 10, 2007, relinquishing command in Iraq to General George Petraeus. In September 2007, in testimony before the U.S. Congress, General Casey said "the current demand for our forces exceeds the sustainable supply. We are consumed with meeting the demands of the current fight and are unable to provide ready forces as rapidly as necessary for other potential contingencies" - underscoring in a public hearing the strain that the continuing Iraq War is placing on the U.S. military.
In his previous assignment, he was the Commander, Multi-National Force - Iraq, a coalition of over thirty countries, from July 2004 until February 2007. General Casey was commissioned a second lieutenant of Infantry from Georgetown University School of Foreign Service in 1970. Throughout his career, he has served in operational assignments in Germany, Italy, Egypt, Southwest Asia and the United States. He has commanded at every level from platoon to Division.
