It's not as binary as most of replies here suggest. Huge open maps like crossing, langres, minsk or even bystraya are perfect for light vehicle play. And that is the matter where usf excell so these are not as bad as it may seem, if you can adapt to the map those maps can be perfect for that faction.
Personally I veto stalingrad with all factions and bystraya if I am getting sick of it as it sadly happens.
It may be open for the vehicles, but it's also open for the AT guns,snipers,LMGs,HMGs, even scout cars,etc.
And also have obvious flank routes that are easy to shut down.
Not only that but if the game lasts 30+ mins the middle of these maps turn into no mans land,which isn't USFs forte.
Or drive straight into their kill zones And abuse smoke.
Not saying you can't win on these maps
, it just mAkes it easy for axis to just look at you and shoot you. Which isn't fun when nothing you have can take many hits.
