SAN ANTONIO (AP) — A battalion commander says the soldiers came under increased risk from roadside bombs while searching for Army Sgt. Bowe Bergdahl after he disappeared from his post in southeastern Afghanistan six years ago.

Col. Clinton Baker testified Thursday that the increase was due to soldiers being sent to places that they ordinarily wouldn't have gone. Baker was the last of the three witnesses called by military prosecutors during Bergdahl's Article 32 hearing. Bergdahl's lawyers will begin presenting evidence and calling witnesses when it resumes on Friday.

All three prosecution witnesses stressed the difficulties caused by Bergdahl's June 2009 disappearance. Prosecutors say the evidence warrants Bergdahl facing a court-martial on charges of desertion and misbehavior before the enemy. The misbehavior charge carries a possible life sentence.
