Nicolae Ciuca, the Romanian Chief of Defense, and U.S. Army Col. Steven Shepherd, commander of the Black Sea Area Support Team, observe an air show by the British and Romanian air forces at Mihail Kogalniceanu Air Base, Romania on July 13, 2017. The Romanian president was on a tour of the air base during this year's Saber Guardian, a multinational training exercise involving the US and its NATO Allies and partners as they foster readiness and enhance teamwork across eastern Europe. The air show displayed the abilities of each country's fighter jets as well as how cohesively they work together. (Photo by Army Pfc. Nicholas Vidro, 7th Mobile Public Affairs Detachment)
