U.S. Airmen, equipment, and F-16CJ Fighting Falcon aircraft assigned to the South Carolina Air National Guard’s 169th Fighter Wing successfully finished three weeks in Sweden for Arctic Challenge Exercise 19. ACE 19 is a biennial Nordic aviation exercise that serves to amplify scenario-based defensive training and interaction between countries across northern Europe. “Training exercises like ACE 19 are critical because this region is full of potential adversaries with a robust air threat. And the way that threat will be dealt with is by all the partner nations coming together. Interoperability is what we sought to work on and grow,” said Col. Akshai Gandhi, 169th Fighter Wing Commander.
