this is NOT the 101st that I knew. I'm wondering if this isn't some vets enhancing some war stories for some reporters. If this was going on at the scale stated, I can't believe this could have been kept quiet within the battalion, not even getting into the rumor mills that the Army is famous for.
I too, never saw any necklaces of ears or fingers. Like James said, who the Hell would want to smell rotting flesh hanging around your neck, assuming the officers or NCOs would permit it. I'm labeling this "BULLSHIT" until something more confirmed as documented surfaces.
