Ken Rosenbaum keeps a small frame shop in the Helena Valley. The Vietnam veteran, who struggled with PTSD after the war, had three sons go to Iraq.

One of them came home a much different man.

"He came home all messed up," Rosenbaum said of his youngest son. "My kid is still in combat, there's no doubt about it."

Rosenbaum doesn't beat around the bush, nor is he a stranger to war. He flew helicopters in Vietnam, Cambodia and Laos in 1970 as a member of the Army.

What gets him choked up aren't his memories of dangerous flights. What has stayed with him all these years are the bodies -- dead soldiers he flew in to retrieve.

Rosenbaum's own struggles with PTSD helped him see the symptoms in his youngest son. When the soldier returned from Iraq, his problems soon began.

His son got a DUI and was charged with domestic assault on his girlfriend. Charges for aggravated assault stemming from a nasty bar fight followed. He drank too much, and released his anger in volatile bursts.

"He couldn't talk about anything other than the war," Rosenbaum said. "He went crazy out here a couple of times. He doesn't trust anybody, especially women."

The soldier, 24, was finally committed to a clinic in Sheridan, Wyo., that specializes in treating veterans with post-combat stress.

"He was exposed to an awful lot," Rosenbaum said. "You can't just go killing people without something happening to you."
