What are the hallmarks of an adaptable military force? What types of leaders best create cultures of adaptability in their formations? How do such forces employ rapidly changing technologies? And how does doctrine drive or limit adaptation? Dr. Nora Bensahel and retired Lt. Gen. Dave Barno—authors of the book Adaptation Under Fire: How Militaries Change in Wartime—join this episode to discuss these questions and more. The episode was originally recorded and released in early 2021, and returning to it helps to provide a framework within which to understand the ways in which adaptation—or failures to adapt—have played into the ongoing war in Ukraine over more than four months.
