NATO's mega-exercise in Europe

On October 19, NATO kicked off its largest military exercise in over a decade with an opening ceremony in Tripani Air Base, Italy.

The exercise, called Trident Juncture 2015, includes approximately 36,000 troops, over 140 aircraft, and 60 ships from more than 30 nations.

The exercise's participants include both NATO countries and nations that are close with the various NATO states but aren't officially being part of the alliance, such as Australia, Austria, Finland, and Ukraine.
