It doesn't have infinite AP, AFAIK, what it has is the ability to create a minimum number of units without paying APs for them if you are using a Logistics Help level of 110 or more for the Soviet AI. This is documented in the rules. Are you playing with 110 (challenging level) help?
Nope, played with default settings. But I still am of the opinion that the AI has more or less unlimited APs.
If you look into the save I posted in the tech forum thread you'll see that during the 2.5 years of the '42 campaign, the Soviet AI lost 450 corps + alot of other units. It must also have a couple of hundred additional corps on the line as well, as the AI is still strong and healthy. Now, I'm unsure on the APs it would take to create such a mass of units, all I can say is that after crunching a big pocket with 70+ units, a few turns later the AI is up to its old strength again, so it for sure never has any lack of units to funnel its unlimited resources into. And it takes APs to create most of those units, right ?
With unlimited resources I mean everything except manpower seems unlimited, again if you open that save from my active tech thread and have a look at the Soviet arm, oil, fuel, resource pools you will see that, despite the Soviets having lost so many strategic centres, their resources are still basically unlimited which I would call a megabug.
