In eastern Ukraine, Hodges said, there are about 35,000-40,000 Russia-backed fighters, and around 4,000-5,000 are actual Russian military officers or commanders.
He said many of the tanks and vehicles operated by both Ukrainian and Russia-backed forces are now covered with reactive armor, a specialized type of plating designed to protect against rocket-propelled grenades and weapons other than small arms.
He also said Russia-backed commanders have honed tactics that include using drones, artillery, and electronic warfare. That's allowed Russians forces, for example, to eliminate Ukrainian mortars and artillery units. He said one Ukrainian unit that was using a U.S.-supplied radar was taken out by Russian rocket fire with surprising speed.
“The [Russian] electronic warfare capability; again that’s something we never had to worry with that in Afghanistan and Iraq. The Ukrainians live in this environment,” he said. “So you cannot speak on a radio or any device that’s not secure because it’s going to be jammed or intercepted or worse, it’s going to be found and then it’s going to be hit.”
“Certainly we have the capability to show everybody what Russia is specifically doing in the Donbas, that would be helpful to keep pressure on Russia, to live up to what they've said they're going to do,” he said.
