Combat Controllers from the U.S. and Polish forces conduct a military free fall during a culmination exercise near Krakow on Dec. 5, 2018. The exercise follows a two-month training in which the U.S. Air Force Special Operations Command’s 321st Special Tactics Squadron assigned to the 352nd Special Operations Wing in England, and the Polish Special Operations Combat Control Team, share their best practices in order to build upon the Polish Special Operations Command’s ability to conduct special operations air land integration.
