There was one brave soldier. He was new in the company, all of his mates they gave him a nickname that was noob. He felt bad for the nickname, but He said to himself, on my first mission I will prove that I'm done. One day the commander gave a mission to the company, that was rescue an old member of the CIA who knew secret information. The Taliban's has this important person and his nickname was fostrock. The soldier knew that was his mission to change the nickname, this mission was so hard to do, many of the soldiers could die in the mission, but this brave soldier has the courage to do it. 

The day of the mission all of his mates were frightened, because their enemies was so strong and powerful, this is the time to show who I am told the soldier, he shoulder the weapon and looked straight before them, and he said I will save you brothers in arms. He go alone to the dark forest, he was afraid, but the adrenaline running in his blood, makes that he does´t thing in this situation. He entered in the building, and kill a lot of enemies, but he complete his mission and save the important person. When He returned to the trench all of his mates clap. He was proud of what he had done and all the mates said to him that He has a new nickname that was The Brave.
