Vehicle customization is much bigger, deeper, and more tactical in nature than in previous Battlefield games. With over 80 unlockable specialization upgrades spread over the different vehicle classes, there is plenty of room for you to tailor your rides to fit your needs. Each customizable vehicle class has three unlock slots: one secondary weapon slot, one gadget slot, and one upgrade slot. By playing a vehicle class and getting kills with it, you gradually unlock more specializations for that particular vehicle class. Vehicle customization in Battlefield 3 is just as deep and tactical as the weapon customization showcased here on the blog last week. For every choice you make in vehicle customization, you are effectively gearing up for a specific combat role and leaving something else out. In the Russian fighter jet, do you go with anti-air missiles to dogfight enemy air targets, or would you rather mount a handful of laser guided air to ground missiles as your secondary weapon to harass opposing tanks? Do you equip it with IR flares to avoid missiles, or would you rather take your chances with the fire extinguisher in case you get hit?
