“Sergeant Bergdahl slipped away from his outpost, the former senior officer said, possibly on foot but more likely hiding in a contractor’s vehicle. “He didn’t walk out the gate through a checkpoint, and there was no evidence he breached the perimeter wire and left that way,” the ex-officer said... “He had sent all his belongings home — his computer, personal items,””
It’s evident he’d planned for it, hopefully the prosecution doesn’t let him plea bargain down so he just gets a slap on the wrist.
Or he went through the back gate into the Afghan National Police post that the US outpost was next to, and began his walk to India ‘or higher HQ’ from there.
