U.S. prosecutors say Blackwater Worldwide security guards used machine guns and grenade launchers in an attack on unarmed Iraqi civilians, some of whom had their hands up.
Prosecutors unsealed a 35-count indictment against the five guards Monday for a 2007 shooting in Baghdad. The guards surrendered in Utah, where they will argue the case should be tried.
The Justice Department charged the men with manslaughter, attempted manslaughter and using a machine gun in a crime of violence. The latter charge carries a 30-year mandatory prison sentence.
A sixth guard admitted in a plea deal to killing at least one Iraqi in the shooting.
U.S. attorney Jeffrey Taylor says the guards were authorized only to take defensive actions.
Blackwater is based in Moyock.
