*as Sgt Drifter walked down the narrow halls of the navy ship, he found the chow hall and sat down with his friends to enjoy his meal and maybe his last but he wasnt really afraid of death, as long as he died next to his comrades with a rifle in his hand, he could stare down death* " he sits down with a group of people to enjoy his meal."
