they can
mkb (battlescope) is free at lv26 with sniper
avs36 (battlescope) is free at lv 26 with sniper
(and I would like to add that f2p vehicles are definitely better than many stuck in full access)
now, mkb of snipers is definitely better than that of engineers because of the battlescope, on the other hand all soviet semi-automatics after svt38 have all and I say all the same statistics, and only changes is the automatic fire (which is shit) the whole question of pw2 can be summarized in, ppsh41 not free=scam
Jumbo cant pen Panther.
Was talking about Moscow. HEAT Panzer IV can pen whole T-50, normal/ free one not everyhwere, only mantlet.
Even better than PPSh since 2hk and better accuracy and at least MG13 Drum has more or less the same clip size as the PPSh.
Sounds like Asymmetry at its best.
If you want to kill panthers (as a tank), bring a tank destroyer M10, not an infantry support tank. If you want to pay 50-100 bucks to buy you the luxury of being lazy about the tool you pick, it gets pretty expensive when your Firefly gets wiped easily by a detpack, faust, piat, insert free tank here, bomb, or just someone who shot first.
No mag size, accuracy, special round will help you if you get jumped first or counter played. To me that’s not worth dishing out a wad of cash for (unless its just for sheer love). Ill just counter pick from my free squads and be just as content.
cost to performance not worth it. Only exception id make is Panzer IV HEAT for those few times I actually see a t50 but again. easily counter picked.
Just Remember, OP happens (evil)when good people dont counter play (do nothing) 
Firefly is really good faster then the jumbo better ap and decently armored too
Not the same class of tank. That’s my mistake for not saying M10 in the original post as a comparison. I said Jumbo because I would choose the jumbo instead of the firefly BECAUSE id be immune to most enemy tanks except the occasional panther, and I pick tanks to control infantry…not tanks.
I don’t know about anyone else, But for every one high level tank I see (in any campaign) I see 10 low level tanks. Meaning I dont need to pay for that premium tank for the 1 time I might see a panther . If a high level tank shows up, I got so much other gear to take care of it.
1 in 10 times my jumbo would be vulnerable vs fire fly vulnerable to near everything (tank wise)
