Missing NATO vehicles in conquest on some maps

HI, I've noticed that there is no Bradley and Apache on some maps in Conquest mode and sometimes on Breaktrough. It's so annoying when PAX have their IFV and Attack Helis and you can't fight them with your vehicles. Icon of Bradley and Apache is showing on respawning map, but they just dont works. Why no one in EA noticed that in the most important mode CONQUEST there is bug with those vehicles in NATO it's just unfair that one side have them normally but other don't. Need to fix that ASAP.
