This week on Weapons & Warfare, we’re in Washington, D.C.,

for the Association of the U.S. Army’s annual conference and exhibition. Host

Ryan Robertson catches up with the Army’s senior leadership and civilian

counterparts to get a feel for where the nation’s largest and oldest fighting

force is headed in the face of ever-changing threats worldwide. Plus, Northrup

Grumman introduces a new duel-feed Bushmaster chain gun.
