So opponent dont use falme ht/222/luhs/aaht ?
Keep in mind have mainly played 2v2s recently and only one Soviet v OKW matchup I can think of.
Luchs didn't really push me around a whole lot. I lost engagements due to the luchs, but I was close enough to T4 at that point I didn't bother going for anything T3. I did utilize Guards though. However, I also placed mines early on. While my opponent saw, I think it still made him too paranoid to send his Luchs anywhere that offensively. They didn't use AAHT. Also I actually haven't seen AAHTs being used in 2v2s either.
The 222 is the only thing that has consistently made me actually feel the need for Guards before I could tech for anything. But as long as I keep my units in cover they don't push me off nearly fast enough. The early game dominance keeps that fuel income heavy and steady, and usually guarantees being able to respond to whatever the Axis manages to scrape together. I mean, here's the thing: against a good 222 I'll lose the VP advantage for a while, but generally I don't see my fuel threatened when I'm against Ostheer. I'm usually denying most, if not all of their territory early on.
Interestingly enough OKW usually is able to harass resources with their kubel. The kubel always dies eventually but the income they can deny usually gives OKW the breathing space they need to tech at somewhat a similar pace. Having to send my otherwise flanking/harassing penal battalion to handle the kubel can be such a pain.
As for the Flame Halftrack I haven't fought against it yet in 1v1s, but I see it in 2v2s. In one of those cases my british ally immediately AECed its face off. Otherwise I've gone T1>T2, then teched the moment I had enough fuel to churn out T34/85s til victory by VP.
And so I have yet to have any inclination to get PTRS and AT Satchels on Penals because Guards (specifically Guard motor) has always been a superior decision. Every light vehicle rush I have faced either came too late that I was close enough to T4 to just temporarily sacrifice the map control, or they didn't have significant ability to keep me off the field.
I think it's worth noting I also spam mines as Soviets. I do it in plain sight sometimes to make sure my opponent isn't comfortable rushing or flanking anywhere without sweepers.
