Unarmed Troops Scrambled to Get Away From Chattanooga Gunman

Three to five minutes was all it took 24-year-old Muhammad Youssef Abdulazeez to punch through a gate with his rented Ford Mustang and blast his way into a Navy-Marine reserve center, killing four Marines and mortally wounding a sailor. Officials on Wednesday released new details of last week's brazen assault in Chattanooga, describing a chaotic scene of mostly unarmed Marines scrambling to escape the man who approached with an assault rifle, a handgun and a vest full of extra ammunition.
