Firefighters stand in the rain to honor fallen US servicemember killed in Kabul

Firefighters stood atop their truck in heavy rain, dozens of people lined up on overpasses from Knoxville to Fairfax County, and many others joined in an escorting motorcade—all to honor fallen U.S. Army Staff Sgt. Ryan Knauss, one of 13 service members that were killed in Afghanistan during an attack on the Kabul airport last month.
