In a survey of U.S. troops in combat in Iraq, less than half of Marines and a little more than half of Army soldiers said they would report a member of their unit for killing or wounding an innocent civilian.

More than 40 percent support the idea of torture in some cases, and 10 percent reported personally abusing Iraqi civilians, the Pentagon said Friday in what it called its first ethics study of troops at the war front. Units exposed to the most combat were chosen for the study, officials said.

"It is disappointing," said analyst John Pike of the Globalsecurity.org think tank. "But anybody who is surprised by it doesn't understand war. ... This is about combat stress."

It's got to make you feel really good about those extended tours, doesn't it? But it gets better, once they are home, now some troops have to battle for custody of children.
