The way the Ranks work is very simple. If your join the clan early on, know somebody in the clan, or are good, you join/get promoted easily. If you are a random person off the street with no skillz you join at L5 Private. It is easy to climb to L1 Private but you have to prove your good enough in a game (you against 3 comps. You dont have to win, you just have to do well.) to become an officer. It would do you well to have an officer recommend you, too. Heres the clan, more every day. Go to the join page to sign up
