A National Guardsman portraying a Guantanamo prisoner says he was badly hurt by fellow soldiers, according to this story from the NBC affiliate in Lexington, Kentucky:

...In January 2003, [Sean] Baker was a member of the 438th Military Police company in Operation Enduring Freedom at Guantanamo Bay, where he says he was "given a direct order by an officer in the U.S. Army" to play the role of a detainee for a training exercise....

Baker says what took place next happened at the hands of four U.S. soldiers - soldiers he believes didn't know he was one of them - has changed his life forever.

"They grabbed my arms, my legs, twisted me up and unfortunately one of the individuals got up on my back from behind and put pressure down on me while I was face down," said Baker. "Then he - the same individual - reached around and began to choke me and press my head down against the steel floor. After several seconds, 20 to 30 seconds, it seemed like an eternity because I couldn't breath. When I couldn't breath, I began to panic and I gave the code word I was supposed to give to stop the exercise, which was 'red.'"

But, Baker says, the beating didn't stop. "That individual slammed my head against the floor and continued to choke me," he said. "Somehow I got enough air, I muttered out, 'I'm a U.S. soldier, I'm a U.S. soldier.'"...

"I sustained an injury to my brain a traumatic brain injury which has caused me to have a seizure disorder I deal with daily," said Baker.

Baker's traumatic brain injury is outlined in a military document in his possession, which says the injury "was due to soldier playing role as a detainee who was uncooperative."...

Baker, by the way, looks as if he'd be pretty tough to hurt.

What were we training these guys to do? And don't tell me they gave this guy a permanent brain injury because they watch too much Internet porn.
