Mental War(D)

How did I get here?. I had never held a gun and there I stood, gun in hand, defending some meaningless bunker on a hill. I looked in the eyes of the enemy across a stagnant foggy field. Sunlight would occasionally dart in and out and the enemy became visible. I looked in their eyes and they were no different than me. A commander called from behind a vague command. I shot a man in the stomach. His headed twisted in dismay. I felt sick and vomited violently. A bird sang a song of harmony. This was not my war.
