Who is Colonel David Hudson from Black Friday and what is their importance?

David Hudson was an officer in Vietnam and becomes leader of Green Band. Hudson was put on the fast track to officer status and was selected to receive some specialized training above and beyond the normal training. As Arch Carroll would eventually learn, Hudson was trained by the U.S. Government to be a terrorist. He was help prisoner in a POW camp and later lost an arm in Vietnam. Hudson is generally in strict control of himself and his emotions, though he does begin to feel something for the hooker, Billie Bogan. Hudson completes the Green Band mission, but then turns renegade against those who masterminded the plot and blows up their houses as well.
