(NEWSER) – Joining the Army wasn't Bowe Bergdahl's first military experience: He was in the Coast Guard for 26 days. Due to his departure before 180 days of service, he was given an "uncharacterized discharge" in 2006, friends tell the Washington Post; military records confirm the story. He left due to psychological issues; friends were reportedly concerned about him at the time. How he was able to join the Army in 2008 is unclear, the Post notes. A discharge related to psychological health would generally prevent future recruitment.
