US military prosecutors are seeking the death sentence for a soldier who is thought to have massacred Afghan civilians.
Sgt Robert Bales is accused of carrying out the attacks in March this year, killing 16 people, including nine children.
Several soldiers testified, saying he returned to the base covered in blood.
Sgt Bale is charged with murder, attempted murder, assault and using drugs and alcohol while deployed.
Afghan witnesses testified via video link, including a seven year old girl who said she hid behind her father as he was shot and killed.
