A trailer for Battlefield 4's new Battlelog has leaked, featuring some interesting integration with mobile and tablet devices, such as customizing your loadout so that you're cocked, locked and ready to roll as soon as you start up the game. The tablet can also be used as a mini-map and to set attack points. Watch it now before ninja commando lawyers get to it.

Update: Replaced leak with official trailer.
