The authors of the new book Adaptation Under Fire: How Militaries Change in Wartime will speak Nov. 2 during a webinar hosted by the Association of the U.S. Army.

In the book, retired Lt. Gen. David Barno and Nora Bensahel write about how every military must prepare for future wars without really knowing what the future battlefield will look like—and because of this uncertainty, militaries must be able to adapt quickly in order to win.

Adaptation Under Fire identifies characteristics that make militaries more adaptable, illustrating those points using historical examples and the recent wars in Iraq and Afghanistan.

The event, part of AUSA’s Thought Leaders series, begins at 11 a.m. Eastern.

The event is free, but registration is required here.

Barno and Bensahel are both visiting professors of strategic studies and senior fellows at the Philip Merrill Center at the Johns Hopkins School of Advanced International Studies. They also are contributing editors and columnists for War on the Rocks.

Barno served in the Army for 30 years, including as the commander of U.S. and coalition forces in Afghanistan from 2003 to 2005.
