Hey Neris, what Planet Smasher said is really good for in-game mechanics, but something frequently overlooked is applicable to any videogame you're playing. Be focused on your game 100% if you can. If that means turning off your phone for the duration of the game, then do it. Being focused really improves your micromanagement: dodging grenades, pressing the retreat button, etc.
I also recommend using hotkeys. In your options menu, under the gameplay tab, you can change hotkey settings from classic to gridkey. What this means is that the abilities you see in the lower right hand of your screen are where they are on the keyboard: qwer asdf zxcv, and weapon upgrades are tgv. Using hotkeys may seem insignificant, but it definitely helps. Time can really be crucial when you're being shot at, taking artillery fire, etc.
tl;dr focus, use hotkeys.
Also, there are some gameplay features that you'll learn that are more nuanced: Molotovs take forever to throw whereas volks incendiary nade is a fraction of the time. When I first played against Wehrmacht, I found it hard to see the rifle-grenade animation on the grenadiers. One thing that I find useful about the katyusha is to know that the first four rockets of the barrage tend to go a little farther than the next two. I always aim a little high with my barrage as a result of this.
Knowing the timing of enemy vehicles or infantry is also important. If you just got T3 up as Soviets at the 12 minute mark, spending fuel on a T70 is probably a bad idea; there's almost certainly an AT gun on the field or maybe a puma depending on commander/faction/tech. It just takes more practice, more time, and careful observation.
Watch your own replays. Maybe you could've pushed on one half of the map but you didn't because you thought your opponent had a huge army over there when in reality they just built a couple of kubels and capped it while you were fighting a volks and sturmpio.
That being said, here's a recent game my friend Choccy and I played.
While I used three maxims, I had a bit of trouble fighting his double kubels: he was more mobile and could cut me off and go around my maxims, however, this is an example where soft/hard counters are outweighed by micro. There's some classic, aggressive Soviet MG gameplay, particularly in the mid game, that allowed me to bring in enfilading fire on some units on the middle VP. Also, never underestimate the power of the SU76. Soviets have a lot of indirect fire that isn't necessarily superb, but it can be massed to overwhelm one's opponent (not to mention flare vet 1 ability for mortars which makes them super accurate... when indirect fire has vision, it makes the auto-fire [not barrage] much more accurate).
I hope this thread helps you out, and keep uploading replays asking for advice! there's a separate replay review section on the forums I believe, and I saw the mentoring link posted in here as well. Don't be afraid to message people on .org or on steam if you encounter them!
