Just today, the article An Open Letter to the Iraqi People, From Soldiers in the Unit Depicted in the WikiLeaks Video by Josh Stieber and Ethan McCord (AlterNet) appeared. The soldiers were on the ground (not in the helicopter):

“We acknowledge our part in the deaths and injuries of your loved ones as we tell Americans what we were trained to do and carried out in the name of “god and country.” The soldier in video said that your husband shouldn’t have brought your children to battle, but we are acknowledging our responsibility for bringing the battle to your neighborhood, and to your family. We did unto you what we would not want done to us.”
