The still-unidentified Iraqi was shot multiple times in the head and chest last June during a raid on a suspected insurgent hideout near the northern city of Kirkuk.
Private Christopher Shore admitted firing additional shots at the man on orders from Corrales but says he intentionally missed. A panel acquitted Shore of murder, but convicted him of aggravated assault. He's expected to testify against Corrales.
Both men deployed to Iraq in mid-2006 for 15-month tours of duty with their Honolulu-based combat team.
Corrales will be arraigned Monday. The trial is expected to start Wednesday and last three or four days.
