The Department of Defense has a communications and protocol challenge that may get worse before it gets better. But it’s an old challenge – maybe as old as the department. Lt. General David Barno (USA ret.) was senior American commander of U.S. and coalition forces in Afghanistan from 2003 to 2005. He’s now Distinguished Practitioner in Residence at the School of International Service at American University in Washington, and Nonresident Senior Fellow at the Atlantic Council. He and his colleague Dr. Nora Bensahel write for War on the Rocks under the title “The Military Is From Mars, Civilians are from Venus: Avoiding Interplanetary Collisions in the Conference Room.” Gen. Barno discussed the military-civilian communications divide on National Defense Week.
