Battlefield 2142 Easter Egg - Dice-cola

Load up a game of Camp Gibraltar, and go to a place where the ground isn't sand (like the toll station area). Take a look at the ground. You should notice some debris on the ground that seems part of the ground texture (this may not be visible on lower graphics settings). If you lay prone and look at some of the debris, there are some drink cans that say 'dice-cola'.
For those of you who don't know, Dice is the name of the developer of the game
