A US soldier is now pleading not guilty to the kidnap and murder of an Iraqi.
His lawyer said Thomas was only following orders and he blamed repeated bomb blasts for impairing his judgment.
Thomas faces a maximum sentence of life in prison, according to his lawyer, Victor Kelley.
He was also convicted of kidnapping but acquitted of premeditated murder, making a false statement and housebreaking.
Prosecutors said that during a night-time patrol on April 26, 2006, Thomas’s squad hatched a plan to kidnap and kill a suspected insurgent from his house in the town in al-Anbar province.
When they could not find him, they kidnapped Awad who lived nearby, instead.
Others accused in the case have testified that several squad members took Awad to a ditch and shot him to death.
