Topic updated with paragraphs now, sorry
well in the heat of the battle i always seem to forget that little details like using molotov cocktails on conscripts, using smoke grenades, t34 ram ability and more.. well i thing thats normal considering the early stage the game is.
Even since COH 1 my main problem seemed to be the late game, with strong early and mid game when in desperation or something i make wrong decisions or wrong units. Losing the game like yesterday can bring frustration since in the 30 minutes your always a step ahead, good flanking and good combined arms. i think russian tanks sucks right now, but i wasnt able to play or see ISU152 yet, elephants for example are uber strong. i Have made mortars too but german one seem to be stronger, as the AT guns too. MGs in the late game just dont seemed to supress vet german infantry, always died to fast :/
The comeback mechanism may have been the reason we lost the game, i dont know. My teammate made more damage than me but i received more XP, i dont know why lol. I still dont have defined if i like shock troops or guards better, i stil have to play some more games to find out..
Cheers xD
Shock Troops are Guards have very different roles, so it's really dependent on what doctrine you prefer and what style you play. If you have light anti-tank typically, Guards are great. If you have light anti-infantry or few durable units, Shock Troops can be better. I love both of them as units and I feel they fit their roles well.
German weapon teams are stronger but have less men, so you're correct about them being better. Precise artillery, mortars and snipers can deal with them extremely well, often killing them before the enemy can respond. I understand that HMGs may not seem too great, but usually the reason they die is that they are too far ahead. Weapon teams in general shouldn't be used aggressively, and an HMG combined with a tank or squad of infantry can destroy infantry squads without much chance of them causing damage. I don't think veterancy reduces their ability to be suppressed, just significantly reduces the damage they take, which is why HMGs really need to be supported by other units late-game. They won't kill, they'll just suppress so other units can kill.
As for mortars, if you move before the German mortars start trying to counter barrage, you'll be out of range and can barrage again without having taken any damage, so unless they have more mortars than you do, I wouldn't expect you to have much trouble.
Russian tanks are certainly worse than German tanks. The only way to equal them is to get the IS-2 or ISU-152. Still, the T-34 and SU-85 are incredibly strong at anti-infantry and anti-tank respectively, so as long as you have AT guns and infantry supporting them, German tanks shouldn't be a major issue.
As you say, it's still early in the game and there are still many things to learn and remember. Try watching the replay and see if there were any small mistakes you did, like having to use MP on replacing squads because your unit preservation wasn't great. Usually the reason someone loses late-game is not because they don't know what to do, but because of the errors made earlier in the game.
If you want to learn strong late-game strats and mechanics, watch some of the more popular 1v1 replays. Specifically, watch how they transition from a mid-game infantry and weapon team composition into tanks, and especially how aggressive or passive they play with their units. Squad preservation is huge, and if you have more/better vet infantry than your opponent, it can be easy to beat them back (even if you have been losing most of the game).
