A convoy of Afghan Humvees makes its way down narrow roads in urban Afghanistan while escorting an Afghan Army Corps commander in the summer of 2016. From the rear, a Tactical Air Control Party officer witnesses a rocket-propelled grenade rip through the lead Humvee, as a gunner with a heavy machine gun steps in front of the second, unloading the entire ammunition belt into the windshield. With the commander located in the fourth vehicle, time was limited to react.
