The joint aerial training Thracian Thunder was held in Graf Ignatievo Base between January and March 2016. Twelve U.S. Air Force A-10 Thunderbolt II aircraft, assigned to the 74th EFS (Expeditionary Fighter Squadron) were deployed to Bulgaria, as part of the European Theater Security Package in support of Operation Atlantic Resolve. They have trained among Bulgarian MiG-29's fighters and Su-25's attack aircraft.

The pictures in this gallery were taken on 23 of February when two mixed pairs of "tank busters" performed a Close Air Support sortie at low level near the city of Pazardzhik.
