As an instructor, TSgt William Jefferson was known for the impact he had on many of today’s #CombatControllers. #OTD 11 years ago, Jefferson, a #SpecialTactics operator with the 21st STS, was killed in action in Afghanistan when his vehicle encountered an IED. We are grateful for his service and will #NeverForget his sacrifice. #FirstThere #AFSOC #specialoperationsforces #sof #cct #pararescue #sowt #tacp #specialoperations #thatothersmaylive #aircommando
