"In the fields"Early in the story how does O'Brien describe the young soldier?

Cross sees a soldier standing off by himself, shoulders shaking. The ponchos make them all look the same, Cross thinks. He is irritated that he cannot remember the soldier’s name. The soldier is also busy blaming himself for Kiowa’s death. The night before, he had taken out a flashlight to show Kiowa a photo of his girlfriend and figures that this is what attracted enemy fire. “Hey, she’s cute,” Kiowa had said, remembers the soldier. That was right before he was shot.
