I'm not saying that having OS in front of your name helps. I'm saying that you have the ability to do things that others cannot.
I'm saying that is harder to get recognized if you don't play with Seniors and at one point a lot of Seniors were MC so if you played with them you get recognized easier. The whole MC thing doesn't apply to sgt or really even corporal thats why i didn't mention in it in my post. But it did affect getting P.O. quicker than everyone else.
