Sure, just make sure to buff the Zis-3 in rate of fire and accuracy.
Vet 0 Su85 doesn't have issues dealing with heavier armor and with vet, it makes armor irrelevant cause it will only deflect the likes of Ele (Pen goes to 312/299/286)
You mean making the blitz ability an I-win button vs Jackson?
Which one?
OH one doesn't improve combat capabilities so they will still miss and they still need to close the 20 range gap.
The heavier variation of Blitz has inferior numbers (so only relevant to PV). Making the PV, a much more expensive tank hunter requiring to chase (missing) for quite some time before killing it.
OKW one is much more tamer speed wise but instead gains combat capabilities but for a reduce period of time (10s).
As this stats haven't changed in a while, i think it should be correct:
Jackson
Speed: 6.5 Accel: 3 Rotate: 30
OKW PIV:
Speed: 6 Accel: 2 Rotate: 30
OH PIV:
Speed: 6.3 Accel: 2.1 Rotate: 32
OH/OKW PV:
Speed: 6.6 Accel: 2.4 Rotate: 30
Firefly
Speed: 5.3 Accel: 1.6 Rotate: 32
