The Skorpion assault teams were a group of U.S. Special Forces soldiers who worked with Martin Lindros when they went on a mission in the Siemen mountains. Their standard weapon was the experimental XM8 Assault Rifle. It is confirmed that there were at least two Skorpion teams, Skorpion One and Skorpion Two. All members of Skorpion One were killed in an ambush in the Siemen mountains, at the beginning of The Bourne Betrayal.
