A U.S. Air Force general on Monday cited what he called "alarming" moves by the Russian military to beef up its air forces in the years since the invasion of Georgia in 2008 and to establish firm defenses around areas like Crimea.
Gen. Frank Gorenc, commander of U.S. Air Forces in Europe, told reporters he was concerned about Russia's moves to increase the quantity and quality of its aircraft and field unmanned aircraft.
"The advantage that we had from the air, I can honestly say, is shrinking," Gorenc said at the annual Air Force Association conference.
