what this is, when you do go into prestige mode (from level 55) you go back to level 1, you may notice that your rank symbol changes this is because your a higher rank (duh) and from now on your rank symbol changes from now on every time you go to prestige. Also when you go into prestige mode all your challenges are reset (you have to do them all over again) and so are you weapons (so basically you are starting all over again). here are all the rank symbols depending on what prestige level you are in.
