How to grind "Pitch black" title with Ka-50

[Saitama_420]

So I have T-80UD, T-72AV (TURMS-T) also researched T-80UK(still stock so very bad) and I have KA-50
I need like 75% of activity in 3 matches.
Should I go to SIM with just heli and try to bomb base?
Should I put KA-50 into 10.3 lineup and just try get as much or should I go with T-80UK and Ka-50 and try to grind?
Any other advice?

Thanks…

P.s. I dont have other vehicles only KA-50 for this event.

To earn it you should have every vehicle from this bundle (sadly).

I may misunderstood. Just played GRB match with Kamov with 84% activity and got 1/3.
