Bowe was good GI: sgt.

Army Sgt. Bowe Bergdahl was an efficient soldier who at times seemed conflicted about his unit’s mission in Afghanistan before walking off his post in June 2009, his former squad leader testified on Tuesday.

“He executed quickly, efficiently — no back talk, no questions. He kept his weapon clean before and after anyone else would,” said former Sgt. Greg Leatherman at the deserter’s sentencing hearing at Fort Bragg, NC, on Wednesday.

“He wanted to go out and get bad guys.”

Bergdahl, 31, who pleaded guilty on Oct. 16 to desertion and misbehavior before the enemy, could be sentenced to life in prison.

Defense lawyers are trying to avoid any prison sentence for the Idaho native, who was held captive by the Taliban for five years before being released in a 2014 prisoner swap brokered by the Obama administration.

Under cross-examination, Leatherman added that Bergdahl complained a lot about the military hierarchy and that the unit was not aggressive enough against the Taliban.

“He wasn’t sold on the mission we were fighting,” Leatherman testified.

Another witness, intelligence analyst Amber Dach, testified that Bergdahl provided valuable information from his time in captivity.

“It reshaped the way we did intelligence in that area,” Dach said.

Bergdahl has no plea agreement with prosecutors, leaving his sentence up to the judge, Col. Jeffery Nance.
