This paper, by Michael O'Hanlon of the Brookings Institution, reconstitutes SSI's Letort Papers series. This group of publications include papers, retrospectives, speeches or essays of interest to the defense academic community that may not correspond with our mainstream policy-oriented publications. In this Letort Paper, Dr. O'Hanlon suggests how reductions in various weapons modernization programs and other economies might release funds for the critical needs of U.S. ground forces.
