Six weeks after his Taliban captors handed a dazed-looking Army Sgt. Bowe Bergdahl
over to U.S. Special Forces commandos, the 28-year-old, who spent five years as a prisoner in Afghanistan, is returning to life as a regular Army soldier on a base in San Antonio, Texas.
"Sgt. Bergdahl will be assigned to administrative duties here at Army North Headquarters," Army spokesman Don Manuszewski tells PEOPLE. "He'll be performing basic duties commensurate with his rank that might include driving senior people, mowing lawns or similar assignments. It really depends on the situation."
Bergdahl, who has reportedly been grappling with psychological issues, has been receiving medical treatment and counseling since his release from captivity in a controversial trade for five senior Taliban prisoners held at Guantanamo Bay detention camp. He will live in noncommissioned officer quarters for an undetermined period of time until he is reassigned.
His transition to a regular soldier's job marks the final phase of his "reintegration process," says Manuszewski, who adds that "the Army investigation into the facts and circumstances surrounding the disappearance and capture of Bergdahl is still ongoing."
It appears that Bergdahl has not yet spoken with his Idaho-based parents – who waged a lengthy public campaign to secure his release – since being freed. In the coming weeks, he will reportedly meet with Maj. Gen. Kenneth R. Dahl, who has been tasked with uncovering the details behind how Bergdahl was taken captive in 2009 and why he had apparently left his remote outpost in Afghanistan.
