You do realize that things like hoorah, molotov, snipers, clown car with flame or snipers, mortars exist in this game.
that stuff is good and all, but when I manage to use it effectively is just because of errors from the german player:
hoorah+molotov: german player setup the mg42 facing the wrong way (with ~180° range this means that it's probably facing his own base).
mortar: maybe will deny ONE area to germans, but very slowly while you are giving up all other areas and capping power.
m3+flame: german player has unsupported mg (usually an immediate faust goes down, not to mention two mgs can just destroy the m3 with direct fire).
m3+sniper: 440mp and 20fuel, comes later, takes about one minute to take down a 240mp mg. while you're busy doing this all the other mg42s in the map tear apart everything with no problem. after that minute a scout car shows up and you can park them at your base.
just sniper: same as above. plus, even with attack move at max range it will get suppressed by the mg's range sometimes.
even if you manage to kill and even capture that mg it's no big deal for germans, it's a 240/480 mp loss, they can recover with no trouble. same if you destry the scout car or the first PIVs/Ostwind, while as a soviet if you lose your M3 or your first su85 you might as well surrender cause you've lost the game.
I've tried playing differently recently, going with Maxims, ZiS, and T34 spam, it might work sometimes but, again, you have to get lucky and rely on german errors: dislocate successfully and mg with ZiS barrage, manage to retreat the first couple T34 when they get low health and repair them so they can maass with the others later.
