A number of U.S. military officers are being charged or disciplined in the ongoing investigations into Haditha, Hamdania and other alleged atrocities.
A Marine lieutenant has been charged with assault; two officers have been relieved; and an Army colonel has been accused of ordering soldiers to "kill all military-age males."
More such charges — possibly against generals — are expected as four separate investigations wrap up.
Top military leaders are troubled by what they see and some say the cases are worse than Vietnam, when fairly few officers were charged. They say a bitter, long-running insurgency is part of the problem — and that the military needs refresher courses in the laws of war and professional ethics.
