LSG's rank progression follows that of the US Army. Promotions are based on a member's accumulated point count. The ranks in LSG are broken down into four tiers, each containing several ranks. Each tier's rank images have a different color background to help easily distinguish them. Unlike the real military, each rank in a tier carries the same authority - a Colonel here has no more authority than a 2nd Lieutenant. This is to help with simplicity, and to allow each tier the opportunity to have the satisfaction of continual progression.
Points are awarded for participating in the clan. Attending squad practice or clan events, posting on the forums, and doing other things that get you involved with the community.
