As you gain EXP by playing games, you will rank up. Your rank is an indicator of how long you have been playing Combat Arms. You can unlock certain equipment only by attaining a certain rank. Although it denotes your experience with the game, it doesn't necessarily denote your skill level. Only a certain number of people are allowed to hold the four highest ranks. Otherwise, you will only rank up and never rank down. When you rank up, you also gain some GP.
The following table lists the ranks in ascending order, as does the image on the left with the rank insignias.
