were they used was that the joke question?
yes they were against the russians and very sucsesful also romania had later 109g4 and 6 as well as home made fighters.
the americans made the mistake when attacking the oil refinery at polisti assuming romanian ftrs would be useless.
check how many p38s were lost against the romanian home made ftrs on one raid alone.
yes they were uses and yes they were well flown
