With Soviet there's a huge amount of overlap between doctrines, so picking the right one means fixing several doctrines in one go.

Therefore, the doctrine I'd suggest for an overhaul is Anti-Infantry Tactics.

Anti Infantry Tactics contains Shock Troops, the KV-8, Incendiary Artillery Strike, Fear Propaganda Artillery and Recon Overflight. The KV-8 and Shock Troops in particular are often complained about as weak.

That gives it:

20% overlap with Soviet Industry (KV-8 flamethrower tank)
20% overlap with Shock Motor and Soviet Shock Army (Shock Troops)
20% overlap with Conscript Support Tactics (Incendiary Barrage)
40% overlap with Counterattack Tactics (Recon, Shock Troops)
40% overlap with NVKD Rifle Disruption Tactics (Recon, Fear Propaganda)
60% overlap with Shock Rifle Frontline (KV-8, Shock Troops, Incendiary Artillery)

Yes the mortar helps unless OST builds their own which they typically do and it counter batteries yours. Really some kind of flame weapon works best but USF doesn't get one.

If they're investing into defending a single building to the point where you can't barrage it then go cap their cutoff. They'll have very little to defend it with.

God help you if your OST opponent rushes an MG42 into a building early because you aren't getting it out anytime soon.

That's literally what the T0 mortar is for.

You can't take down a Volks squad that's in green cover with an equal number of Riflemen out of cover.

Attack one Volks squad with two Rifle squads and their advantage doesn't matter: you'll still win and then that green cover is yours.

Also remember cover is directional: flank or close to within ten metres and the cover is rendered useless.

A third option is to drive them out of cover with grenades, flamethrowers or a mortar.

Sadly in most games there is that one easy, over-powered tactic. Not much you can do apart from sink to their levels.

If this strategy were truly effective you'd see it at top levels. You don't.

No, the true power in FateFairy's strategy is surprise: nobody expects this roving mob of Scout Cars and typical build orders don't work against it. You've got to adapt: you've got to come up with a counter-strategy on the fly and most people struggle to do that.

Given his mainline infantry is the MG42 it's very difficult to rush the map, so don't. Play bite-and-hold: once you've taken a key position, set up some green cover and camp an infantry squad in it. Once green cover suppression resistance kicks in an MG42 can no longer defeat them.

If you get the chance, kill the MG42s and steal them. It's very hard for an MG42 to push an MG42.

The Scout Car horde is the true challenge. The first thing you need is a weapon that'll best them from range and force them to close in, like a light tank or an AT gun. I used a T-70. When I lost it, I built another: this many Scout Cars means they're not bringing out a medium tank any time soon. The purpose of this weapon is to force the Scout Cars to close in: then you use the real counter to the horde.

Snares.

The Scout Car Horde only works because the injured Scout Cars can retreat, meaning the blob doesn't bleed fuel and manpower. Take away their mobility and they can neither swarm nor run.

Remember that this strategy's endgame is the Tiger Ace, so make sure you've got a heavy AT response out by 17CP. I used two ZiS guns and an SU-85.
