Running because is life depends on it him making it to any trench. He reaches it with 13 seconds to spare. But, he soon realizes the ditch doesn't belong to his unit, but to the enemy. The man in different colors reaches for his weapon, but the young man takes his first shot of the war. With a small and quick burst, the enemy is dead. Our young man will make it to his bunk another day with the scarring of his murder, and the enemy will rot in a hidden ditch. War is not a time for second guessing. War is a time fight, not flight.
