Soviet T3's remind me of the KM T3's, just with more speed and less attack power. Very useful for chasing bombers, intercepting T5 scouts (with some fighter control) and being a pain in the ass to any enemy CV unless they have KM/US T4's. :P
I hope the Soviet T4 will be similar to KM also. Then it will be a good choice for all-round fighter/DB CV.
