Pentagon leery of Russia's 'hybrid warfare'

The Pentagon is increasingly concerned about how to combat “hybrid warfare,” the combination of stealth invasion, local proxy forces and international propaganda that Russia used to annex Crimea and destabilize eastern Ukraine, U.S. officials said.

Army Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, on Thursday released the 2015 National Military Strategy in which he cited Russia's actions in Ukraine and said “hybrid conflicts” will persist well into the future.
