On June 9th, we reported on a handful of leaked screenshots that hit the Internet supposedly from an alpha test of Battlefield 4′s Xbox 360 version. On June 13th, those leaked screenshots proved to be true as DICE streamed live pre-alpha multiplayer footage from E3. A detailed look at Battlefield 4 soldier and weapon customization screens later emerged.
Adding to the list of leaked / confirmed customization screens are shown below: Vehicles.
Though only two images are shown for tanks, they appear to have the same armament as Battlefield 3. Attack helicopters are shown to have Zuni and Hyrda Rocket Pods as their primary weapon. Boats have a 30MM HE Shell or Burst Shell as their primary with ATGM and Anti-air missiles as their secondary.
Here is a Youtube vid from the folk at LevelCapGaming. Fast forward to 1:10 for the low down on customizations
