FORT BRAGG, N.C. — Staff Sgt. Jason Jonas says when he goes to bed at night, he is terrified his medication will cause him to oversleep and miss morning roll call again.

His commanders are fully aware that the paratrooper wounded in Afghanistan has been diagnosed with a sleep disorder, because he is one of about 10,000 soldiers assigned to the Army's Warrior Transition units, created for troops recovering from injuries.

Instead of gingerly nursing them back to health, however, commanders at Fort Bragg's transition unit readily acknowledge holding them to the same standards as able-bodied soldiers in combat units, often assigning chores as punishment for minor infractions.

In fact, the unit has a discipline rate three times as high as Fort Bragg's main tenant, the 82nd Airborne Division, and transition units at two other bases punish their soldiers even more frequently than the one at Fort Bragg, according to an Associated Press review of records obtained through the Freedom of Information Act.

"In my 10 years of service I have often seen soldiers mistreated, abused or left hanging, but never have I seen an entire unit collectively, mentally and physically break down its members," said Jonas, a 28-year-old from Tempe, Ariz.

Jonas is one of 11 current or former soldiers who have spent time in Fort Bragg's transition unit and who say its officers are either indifferent to their medical needs or trying to drive injured men and women from the military. Some complain they are being punished for the very injuries that landed them in the unit.

"It is the military's way of dealing with it: 'You're a fake. You need to go back to work,' " said Pfc. Roman Serpik, 25, who enlisted in Duluth, Ga. He said he injured his head and back in a practice parachute jump last April.

Jonas suffered a concussion on a jump in 1999 at Fort Bragg, and military doctors determined that that led him to develop narcolepsy, a disorder that causes people to fall asleep abruptly, he said. He provided copies of his medical profile to the AP to confirm he has the disorder.

He said medication for his condition made him miss formation five times, resulting in a demotion that cost him $400 a month.

Officers in the transition battalion at Fort Bragg's Womack Army Medical Center would not discuss individual soldiers' medical or disciplinary records, citing privacy laws. Speaking generally, they said the way to get soldiers back on their feet is discipline, not accepting excuses.

"Do we hold our capable warriors in transition accountable to these standards, to include the Uniform Code of Military Justice and the various Army regulations? Unapologetically, yes, we do," said Lt. Col. Jay Thornton, the unit's commander.

Thornton said soldiers are "helped, not harmed, by maintaining an appropriate level of structure and military discipline."

Advocates for wounded soldiers question whether the tough-love approach is an effort to get rid of soldiers considered unlikely to return to regular duty.

"It creates a hostile environment where soldiers buckle and take a low-balled disability rating and benefits just to get out when they can," said retired Army Lt. Col. Mike Parker.

The Warrior Transition system was established two years ago to improve treatment of wounded soldiers after the scandal over shoddy conditions at Walter Reed Army Medical Center in Washington.
