Some of the activities of the self-styled "kill team" are already public, with 12 men currently on trial in Seattle for their role in the killing of three civilians.
Five of the soldiers are on trial for pre-meditated murder, after they staged killings to make it look like they were defending themselves from Taliban attacks.
Other charges include the mutilation of corpses, the possession of images of human casualties and drug abuse.
All of the soldiers have denied the charges. They face the death penalty or life in prison if convicted.
The case has already created shock around the world, particularly with the revelations that the men cut "trophies" from the bodies of the people they killed.
An investigation by Der Spiegel has unearthed approximately 4,000 photos and videos taken by the men.
