Camp Lejeune, N.C. ? Marines treated at Camp Lejeune for post-traumatic stress had to undergo therapy for months in temporary trailers where they could hear bomb blasts, machine-gun fire and war cries through the thin walls, according to servicemen and their former psychiatrist.

The eight trailers were used for nearly two years, until a permanent clinic was completed in September in another location on the base, said a Camp Lejeune medical spokesman, Navy Lt. j.g. Mark Jean-Pierre.

The noise from training exercises “shook me up real bad. I couldn’t take it. I almost ran out of there a couple of times,” said a Marine patient who spoke on condition of anonymity because he is not authorized to talk to the media. “My mind couldn’t focus on the treatment. I couldn’t tell the difference between the combat zone and the non-combat zone.”

The allegations became public after the dismissal of Dr. Kernan Manion, a civilian psychiatrist who says he was fired for writing memos to his military superiors complaining of shoddy care of Marines returning from Iraq and Afghanistan with PTSD, a condition that can make patients jumpy, fearful of loud noises and prone to flashbacks.

“These guys are saying, ‘I’m fried and I can’t get out,”‘ Manion said in an interview. Referring to the Fort Hood shooting rampage in which an Army psychiatrist who counseled PTSD victims allegedly killed 13 people earlier this month, he said: “Is there potential for another blowup? Yes, indeed.”

In e-mails shown to The Associated Press, Manion complained, among other things, that the military was not dealing with PTSD properly and that the trailers were infested with bugs and noisy.

“Given that PTSD is the most frequent diagnostic group we see, one would question the sense of locating a clinic in such close proximity to the booming of bombs that shake the trailer, the ratta-tat-tat of machine gun fire and the almost daily occurrence of grunts yelling war cries,” Manion wrote.

In an interview, Manion said the military should have rented a building off base.

Manion was fired in September after working for eight months for a company that has a contract with the military to provide mental health care on the North Carolina base. He said that when he asked the contractor why he was being fired, he was told it was ordered by the Navy.

The inspector general for the Navy’s Bureau of Medicine is reviewing the allegations of inadequate care, a military official said Friday on condition of anonymity.
