American jets killed Iraqi troops with firebombs -- similar to the controversial napalm used in the Vietnam War -- in March and April as Marines battled toward Baghdad.

During a recent interview about the bombing campaign in Iraq, Marine Corps Maj. Gen. Jim Amos confirmed aircraft dropped what he and other Marines continue to call napalm on Iraqi troops on several occasions. He commanded Marine jet and helicopter units involved in the Iraq war and leads the Miramar-based 3rd Marine Air Wing.
