The Pentagon conceded Wednesday that U.S. troops are in combat in Iraq after days of dancing around the characterization following the first death of U.S. service member in the campaign against ISIS. "We're in combat," Army Col. Steve Warren, a Pentagon spokesman, told reporters Wednesday. "I mean, of course, this is a combat zone. There's a war going on in Iraq, if folks haven't noticed. And we're here and it's all around us."
