Matthis Chiroux is the kind of young American US military recruiters love.

"I was from a poor, white family from the south, and I did badly in school," the now 24-year-old told AFP.
"I was 'filet mignon' for recruiters. They started phoning me when I was in 10th grade," or around 16 years old, he added.
Chiroux joined the US army straight out of high school nearly six years ago, and worked his way up from private to sergeant.
He served in Afghanistan, Germany, Japan, and the Philippines and was due to be deployed next month in Iraq.
On Thursday, he refused to go, saying he considers Iraq an illegal war.
"I stand before you today with the strength and clarity and resolve to declare to the military, my government and the world that this soldier will not be deploying to Iraq," Chiroux said in the sun-filled rotunda of a congressional building in Washington.
"My decision is based on my desire to no longer continue violating my core values to support an illegal and unconstitutional occupation... I refuse to participate in the Iraq occupation," he said, as a dozen veterans of the five-year-old Iraq war looked on.
Minutes earlier, Chiroux had cried openly as he listened to former comrades-in-arms testify before members of Congress about the failings of the Iraq war.
The testimonies were the first before Congress by Iraq veterans who have turned against the five-year-old war.
Former army sergeant Kristofer Goldsmith told a half-dozen US lawmakers and scores of people who packed into a small hearing room of "lawless murders, looting and the abuse of countless Iraqis."
He spoke of the psychologically fragile men and women who return from Iraq, to find little help or treatment offered from official circles.
Goldsmith said he had "self-medicated" for several months to treat the wounds of the war.
Another soldier told AFP he had to boost his dosage of medication to treat anxiety and social agoraphobia -- two of many lingering mental wounds he carries since his deployments in Iraq -- before testifying.
Some 300,000 of the 1.6 million US soldiers who have served in Iraq and Afghanistan suffer from the psychological traumas of post-traumatic stress disorder, depression or both, an independent study showed last month.
A group of veterans sitting in the hearing room gazed blankly as their comrades' testimonies shattered the official version that the US effort in Iraq is succeeding.
Almost to a man, the soldiers who testified denounced serious flaws in the chain of command in Iraq.
Luis Montalvan, a former army captain, accused high-ranking US officers of numerous failures in Iraq, including turning a blind eye to massive fraud on the part of US contractors.
Like the Vietnam Winter Soldier hearings, the Iraq and Afghanistan veterans' gripping and often tearful testimony highlighted how the atrocities committed by American troops are not simply down to ‘a few bad apples' but are systematic and continuous and, importantly, a direct consequence of the increasingly bloody occupations.
Ex-Marine Jason Lemieux told how a senior officer had altered a report he had written because it slammed US troops of using excessive force, firing off thousands of rounds of machine gun fire and hundreds of grenades in the face of a feeble four rounds of enemy fire.
Goldsmith accused US officials of censorship.
"Everyone who manages a blog, Facebook or Myspace out of Iraq has to register every video, picture, document of any event they do on mission," Goldsmith told AFP after the hearing.
"You're almost always denied before you are allowed to send them home."
Officials take "hard facts and slice them into small pieces to make them presentable to the secretary of state or the president -- and all with the intent of furthering the occupation of Iraq," Goldsmith added.
Chiroux is one of thousands of US soldiers who have deserted since the Iraq war began in 2003, according to figures issued last year by the US army.
But while many seek refuge in Canada, the young soldier vowed to stay in the United States to fight "whatever charges the army levels at me."
The US army defines a deserter as someone who has been absent without leave for 30 days.
Chiroux stood fast in his resolve to not report for duty on June 15.
"I cannot deploy to Iraq, carry a weapon and not be part of the problem," he told AFP.
