Now this isn't coming from a Soviet PoV, it is coming from someone who recently unlocked the Lvl 19 commander as Germans and since then in both 1v1 and 2v2 I haven't had any reason not to pick this guy ingame?

I don't know if the Opel Blitz Cargo Truck ability in itself causes the balance problems I, albeit granted limited experience, have experienced.

But the massive extra fuel income from the rather easily accessible truck if you have a good early game makes Tigers (why does a Field Support Doctrine have this heavy armor anyway?) rather spammable in the late game, not to mention the munitions. In my last 1v1 I was banking 1500+ munitions in the endgame and 500+ fuel, not sure how long it took but build an additional Tiger and next time I looked when the Tiger was ready I had almost as much fuel as before I build it.
On the munitions, granted I didn't use the off-map abilities as no targets really presented itself.
Before I am going to throw out any cries of "Q.Q he is massively OP, pl0x nerf"

What is your experience with him, both as the Soviets and/or as the Germans? How should the Soviets counter this guy, especially if they lose the early game and don't have time to harass (or at very least thoroughly search as the truck can be placed anywhere and not at the logical center point) my backsectors pumping out resourses?

If I should suggest for anything in this "support" doctrine, remove his Tiger.
Instead give him a Hetzer or something similiar in T3 as a replacement for Stug or as an additional unit.
Seems better suited for his "intended" role on the field. But that was just an idea popping into my head, partly because I am a Hetzer fan

Perhaps, but it would be nice if the Russians (and to a lesser extent Germans, but have covered through bunkers) could make a forward reinforcement and healing point. The FHQ comes to mind here

With the customizable setups and different doctrinal commanders I really feel a need for having better info in the setup screen. What is this "Stuka CAS" ability supposed to be good at, anti-tank or anti-infantry?
Likewise I would like to have unit cost listed in the customizer for each doctrinal unit. Also if it replaces another unit it should show difference if any.
And what does this ability cost in munitions? Is it something I can rely on often or not as often?
