The rewards for leveling up are nothing more than mere skins and so although the game has a vast variety of game types theres not alot in the way of unlockables and customization that say Modern warfare 2 has.
You can actually change your faction, but only in the lobby. I don't know why they didn't mention it but go to the skins, press up and then press X and it will cycle through the factions.
