The successful military is the one that adapts and innovates. Dave Barno, Nora Benhahel, and Frank Hoffman join Ryan to talk about how the U.S. military changes, or fails to do so. They have two new books on the subject between them: Adaptation under Fire: How Militaries Change in Wartime, by Dave and Nora is out now. And Mars Adapting: Military Change During War, by Frank, will be out soon.   (This was recorded before the election results were projected)
