From bottom left clockwise, U.S. Air Force Tech. Sgt. A., Capt. Dan Curtin, former Tech. Sgt. Jeb Corley, and Senior Master Sgt. Chance Barlow stand with a photo of Staff Sgt. Jacob Frazier after the second annual Tactical Air Control Party Association 24 Hour Run Challenge at the 182nd Airlift Wing in Peoria, Ill., March 29, 2013. The men were deployed to Afghanistan a decade ago with Sgt. Frazier when the Peoria-based 169th Air Support Operations Squadron TACP was killed in action. Sixty-two supporters ran the installation perimeter over the course of 24 hours in Sgt. Frazier's memory and raised more than $8,200 in support of the TACP community and their families.
