When the Abu Ghraib scandal initially broke in April 2004, attention focused on a small group of players, composed of the soldiers depicted in the abuse photos and the senior officers directly in charge of them. In the myriad investigations, trials, and news reports that have followed, the scope of the abuse allegations has widened to include locations in Afghanistan, Cuba, and secretive detention facilities at unknown locations.

It would be impossible to catalog every private, sergeant, captain, and colonel involved with the abuses, let alone the long list of CIA officials, government lawyers, contractors, and others involved with the scandal. Instead, Slate has compiled this chain of command, from President Bush down to the soldiers who served at Abu Ghraib and Guantanamo.
