Following his release on May 31 in a swap with the Taliban, Sergeant Bowe Bergdahl underwent medical examinations and counseling at a military hospital in San Antonio, Texas to prepare him for "reintegration" to the army.
"He will now return to regular duty within the command where he can contribute to the mission," the army said in a statement.
Bergdahl will be assigned to Joint Base San Antonio-Fort Sam Houston in Texas, the army said. It was not clear what role or tasks he would be given there.
The 28-year-old soldier has yet to speak to the news media since his release and army officials acknowledged they provided him with advice on dealing with journalists over the past month, which they said was standard practice for former prisoners of war.
