Only if its Karkand and/or Sharqi 24/7. Otherwise vehicles of course. E: And to the "why", because Karkand with inf. only is the best thing that Battlefield has to offer. It's not like vehicles stay around long in urban combat. I think someone got owned by a vehicle too often. This is seriously the shittiest reason for no vehicles that I've ever read. Anyway, almost at rank 45 .
