Hamidullin is accused of leading three groups of insurgents during a failed 2009 attack on Afghan border police and US military forces in Khowst province. All of the insurgents were killed, but Hamidullin was captured alive after opening fire with a machine gun. None of the members of police or military forces were killed in the attack.
The jury is made up of nine men and six women, three of which are alternates. The media was banned from the selection proceedings.
They also argued that the Department of Defense had introduced a new witness with which they were not previously familiar. The judge stated that he will hear motions once the trial begins.
The move to try Hamidullin in federal court has sparked outrage among some Republican lawmakers who argued that military trials should be carried out in military tribunals.
The trial is expected to take five days.
