There are a million ways to be killed or wounded on the modern battlefield: bullets, bombs, drone strikes, a tomahawk-wielding SEAL Team 6 operator. But dogs? For jihadists squaring off with Western forces in the Middle East, the threat is real, and a group of ISIS militants learned that lesson the hard way when they recently ambushed a group of elite British commandos with the Special Air Service in Iraq. And they (or their corpses) have the bite wounds to prove it.
