To say my own personal opinion about this, if you start to clench your butthole over this, then its your goddamn problem:
I dont know if I fancy this new setup. Puma is alright, I mean it was already in the early beta and I was slightly disappointed to see it gone from actual release version. Wirbelwind, OK I guess. I'd personally just have the AA-halftrack instead because theres already the transport version of the same vehicle in the map. Save a texture load.
And then we have a chaffee too.
