The Washington Post, citing an unidentified Army official, said the three-month investigation was also expected to call for changes in how U.S. troops are trained for duty in Iraq.
The investigation is one of two ongoing military probes into the Nov. 19 killings of 24 men, women and children in the town of Haditha, 125 miles (200 km) northwest of Baghdad in an area that has seen much activity by Sunni Arab insurgents.
The newspaper reported that the Army official said there were multiple failures but declined to say whether he would characterize it as a 'coverup' as alleged by Rep. John Murtha.
The Pennsylvania Democrat, a decorated retired Marine, is a vocal critic of the war in Iraq.
The Post said a final report on the probe, led by Army Maj. General Eldon Bargewell, was expected to be delivered to top commanders by the end of the week.
A new focus on training would begin as early as Thursday when Army Gen. George W. Casey, the top U.S. commander in Iraq, was expected to order all U.S. and allied troops in Iraq receive "core values" training, the newspaper reported.
"Not only will leaders discuss how to treat civilians under the rules of engagement, but small units also will be ordered to go through training scenarios to gauge their understanding of those rules," the report said.
There was no immediate comment from a U.S. Central Command spokesman in Baghdad.
A separate ongoing military inquiry found evidence that the killings in Haditha were unprovoked, contradicting an account of the incident by U.S. Marines, U.S. officials said on Wednesday.
The probe by the Naval Criminal Investigative Service, responsible for cases involving Marines, might lead to charges including murder, officials said.
Why don't they train the Iraqi civilians how NOT TO FLY THROUGH CHECKPOINTS!!!!
The use of Murtha's name within an article should instantly nullify it being credible, IMHO.
AS with the Abu Ghareib thing, in this instance OUR milatary brought this out to the public not the MSM. The MSM is picking up on it as they did with Abu Ghareib and Gitmo.
Oh...great, the investigation isn't even complete..but they are sending in groups to teach the troops how to "act"???
Personally, I would rather have them "survive"...
This PC crapola is gonna get more killed.
The MSM makes a big deal everyday about how many deaths of troops there are....and some have already started their countdown to 3000...
BUT, they are also seem to expect the troops to frisk the insurgents before they take any action...
