CSM Troxell Visits Iraq on NatGeo's 'Chain of Command'

The National Geographic Channel continues its ambitious, eight-part documentary series "Chain of Command" on Monday January 22nd at 9pm ET with episode 3, "Shoulder to Shoulder."

The show aims to examine the war on extremism from as many perspectives as possible and this week it travels from Iraq to Colombia to Afghanistan. American officials search for dangerous migrants in Colombia; back home, husband and wife Marines prepare for deployment to Afghanistan.

Filmmakers were also on hand for Jared Kushner's visit to Iraq in April 2017. You've seen the photos of the senior advisor to the president in a flak jacket and now you can watch video of the briefing in this episode.

We've got a great clip from this week's episode. Command Sergeant Major John Troxell, the highest ranking non-commissioned officer in the United States military, visits FOB Union III in Baghdad, Iraq and speaks with personnel in the field.
