Traumatised by the battlefield or the anguish of divorce caused by long absence from home, many American troops in Iraq are increasingly shedding their macho image and visiting Combat Stress Clinics.
Four years ago, following the 2003 invasion that ousted Saddam Hussein, the US military drew together psychiatrists, psychologists, social workers and specialist nurses in spacious buildings where troops could be treated.
For a few hours or maybe days, shattered soldiers can talk over their problems, receive treatment or simply stay in the clinic for a while to rest.
The Baghdad area clinic is near the airport at Camp Liberty, one of the world's largest military bases and home to some 50,000 troops.
Clinic commander Kevin Gormley told AFP: "You certainly still have this macho culture in the military, it's important not to appear weak.
"But I tell you, the stigma attached to mental health and to seeking some help in this matter has been largely reduced."
The importance of early treatment is widely recognised. Studies by the army or independent bodies are emphatic, many veterans of the Iraq or Afghanistan wars show psychological difficulties upon their return home.
One study, by the Rand Corporation, found that some 300,000 out of 1.6 million soldiers rotating back to the United States since 2001 showed signs of psychological problems of varying degrees.
According to the Pentagon, between January 1 and the end of August this year, 21 troops committed suicide in Iraq and another 39 did so after their return home.
