#OTD in 2011 we lost 3 great #SpecialTactics Airmen serving during #OperationEnduringFreedom. TSgt Daniel Zerbe, TSgt John Brown, and SSgt Andrew Harvell were #KIA when their helicopter was shot down during a nighttime rescue mission in Afghanistan. We want to take a moment to remember these courageous #SpecialTactics operators for making the ultimate sacrifice #ThatOthersMayLive #TillValhalla #FallenNotforgotten #FallenNotforgotten
