Bob E. Willis Jr.

Bob E. Willis Jr. is a United States Army officer, confirmed by the Senate as a lieutenant colonel in 2008. While attending the School of Advanced Military Studies, the invitational advanced course following the Command and General Staff College, he wrote a paper, "After the Blitzkrieg: The German Army’s Transition to Defeat in the East", which has drawn considerable interest in its parallel between failure of the German Army to prepare for post-combat operations in the Soviet Union, and is a substantive history of the staff thinking during the Operation Barbarossa invasion. He drew parallels to problems for post-conflict planning in the Iraq War.

He was commissioned from the Reserve Officers Training Corps at the University of Hawaii.
