Ruven stopped walking and looked David up and down. He thought he had made the comment quiet and far away enough to avoid confrontation, but now it was too late. "Who are you? You don't have any name tapes. You're not in a uniform." he asked. Ruven pointed at the Marine. "You know what I see, when I see her? Pedigree." He pointed at the Ghurka. "Pedigree." He continued this pointing at every single soldier here. "Pedigree. Pedigree. Pedigree." Ruven pointed at this beret. "Pedigree" Then he pointed at David. "If you're not in the Army, I don't know where you're from. Judging from your lack of sleeves, and the fact you can't figure out how a safety works on a weapon, you look like you got lost of the way to the gym." Ruven continued "I've worked with Force Recon, Berets, Seals, and the Rangers when they're allowed to run with the big dogs, and I've never heard of whatever unit you're from." Ruven stared at him for a second, and cutting off anything the man was going to try and say, if he replied. "Don't get me wrong, we all got big shoes to fill. But at least everyone has expectations of how big those shoes are when they see each other. You, however? You sure talk the talk, but you ain't walking the walk yet. Maybe we didn't bring any shoes for you to step into." As soon as he finished his dressing down, Ruven turned and kept walking with the group. He made no attempt to disguise what was going on, or to lower his volume, nor did he yell the entire time. He was going to separate himself from David if it meant gaining the trust of the rest of the unit.
