Four-star General Mark A. Milley joins MSNBC’s Morning Joe and talks with Mike Barnicle about a generation of U.S. Army service men and women who have known nothing but war during the last decade and a half. “What have the constant deployments and redeployments—three, four, five, or six of places like Afghanistan—done? What kind of stress have they put on the U.S. Army given the numbers within the Army?,” asks Mike. Listen to General Milley’s explain how the Army has responded to ongoing pressures.
