U.S. Defense Secretary Chuck Hagel has proposed Pentagon budget cuts that could include reducing the size of the Army to between 440,000 and 450,000 troops, from a post-9/11 peak of nearly 570,000. Such a reduction would make the U.S. Army the smallest it has been since 1940. Michael O’Hanlon participated in an event today, hosted by the Center for 21st Century Security and Intelligence, in which expert panelists—including two Army generals and a Marine Corps colonel—discussed the future of land warfare and ground forces.
