The weight of war was too much for one soldier to handle. At Camp Liberty in Baghdad Monday, a U.S. soldier shot five fellow troops to death at a counseling center. The soldier had been disarmed earlier in the day after he got into a verbal altercation with a person there, a source tells ABC News. After the rampage, the man was taken into custody. According to sources, the the shooter was on his third deployment and had recently been referred to the stress center, though he had never before sought help to combat stress. "Anytime we lose one of our own, it affects us all," a military spokesman said. "Our hearts go out to the families and friends of all the service members involved in this terrible tragedy."
