As it stands the USF vs OKW match up is quite largely unbalanced.
I agree with Corsin about US officers being given heavy weapons when they come onto the field is over powered. If the US infantry wasn't already super strong with instant suppression from the Rear Ech troops and rifleman being good at all ranges then maybe it would be fair. However as it stands this is not the case.
The USF can also field the M20 or the AA-HT track around the 5-6 minute mark and they are incredibly strong for how cheap they are. The fact that the M20 crew has a bazooka just makes the unit even more ridiculous. In my opinion it's armor should be the same as an Ostheer 222 scout car even with the skirts. As for the AA-HT it absolutely tears apart all light vehicles and infantry with no set up time at all compared to the OKW Flak HT which comes around the same time. Even the puma has to be wise around it as it does so much damage. Maybe a solution to this problem is add a set up time to the AA-HT and or make it weaker or perhaps slower.
Another suggestion to fix the balance could be putting the panzer 2 into tier 3 instead of tier 4. It seems incredibly strange to have such an average T-70 like tank in such a late tier where only the elite units should be.
Some serious adjustments need to be made to the flak-ht at any rate. It's setup time just makes it useless and will end up being the reason it gets destroyed. As soon as any armor or at gun gets eyes on it it's dead. This is because it will always get two 'shotted' as it can never pack up and run away in time. It's smoke ability will not do it any good against decent players either as they know how to use attack ground.
Hans gets it. It's funny reading all the soviet apparatchiks defending a whole new set of imbalances. Here are some of the main problems for OKW:
Maxim Spam. It's bad if you're Wehrmacht but its on a whole other level as OKW, the Gren's grenades are crap and the infantry gun is a 420mp joke. No flamer, no accurate artillery and no effective grenades make garrisoned units a nightmare to deal with.
Lack of resources. I get that's its fundamental to the design of OKW, and I also realise that in return OKW get a 5 star veterancy system and the Obersoldaten, but the munition cost for grenades, infantry upgrades and even the panther MG is just too much.
Lack of effective AT. Basically if you don't have fuel as OKW then its game over as the only effective AT OKW have either costs a lot of fuel or is infantry based, infantry based AT doesen't do you any good against soviets who have very effective anti-infantry armour, not to mention the KV-8.
Dane hits the nail in the head when he says that OKW has too many specialists and too many units that are just crap. They should move the PZII to the same position as the Jagdpanzer IV, buff the Jagdpanzer IV to be an effective anti-armour unit (Or get rid of it all together and replace it with a unit people actually like) then increase the potency of OKW grenades in buildings.
