Controversy in Afghanistan

The cremation of two terrorists in Afghanistan following a firefight has prompted outrage from the governments of Afghanistan and the United States. The terrorists had been left with the soldiers for at least a day after the fight, and as the soldiers had their instructions to maintain their position, their options were growing slim with rotting corpses in 90 degree heat. Now, rather than typing up why I felt that their decision was not unreasonable, I would like to ask a question. What should these soldiers have done instead, or were there any options other than suffering through one of the worst odors one can imagine?
