I know BIS won't pay licence for real vehicles and weapon names in-game, but i found out about this:
TL;DR : it looks like thanks to EA if a vehicle is 100% true in the visual to the real world counterpart, its not "stealing" nor using without permission because it would be the same as taking a pic from the vehicle. This could be used to avoid the usage of fake names for every vehicle/weapon in the videogame industry (an example would be what rockstar does)
