Can I get some help on Case Blue: Axis #13 Eastern Front.

The reason I had no medals until recently is that is spent it all on Vatutin who helped me complete the allies campaign.

As soon as possible with a healthy army aka at least one arty (double stacked) / heavy arty (preferably full single stack at least), one armoured car (double stacked, preferably) / tank (full single stack) and two inf units (triple stacked).

The Economy you'll accumulate will cover for you when you use air attacks.

Nice to see everyone got a different approach on this mission..IMO, all the objectives required are pretty straight-forward as Vatutin will just spawn at the same place by the place our forces bombard the city,Timoshenko is static at the same position,Stalingrad guarded by a less specialised Chuikov and Zhukov will move towards Stalingrad.The main problem is to sustain your main army til the end.Since many of you already brought enough generals,this should be easy.From my perspective,I placed Bock on the artillery,Rommel on heavy tank and Messe on the medium tank and move them towards Voronezh.Tip:Equip Bock with transport.Take the factory asap and replenish Rommel.When Vatutin appears,flank him and dont stack your troops as he has KV-6.Upon defeating Vatutin,move South to take the two cities above Stalingrad.If possible, use your infrantry to station at the radar to get a better sight of the enemies position.Hire a heavy tank(reinforcement) and deploy Model(or any strong general you have).Soften Timoshenko mainly with Hoth as he can be sacrificed early. Attack Chuikov with ranged troops to lower his morale to male things easier.Bam two objectives finished.Station your Heavy Tanks on the two factories and replenish them.If all your generals are still intact,send Messe towards north to finish Zhukov off and take the city if possible.With all the secondary objectives cleared, defend Stalingrad with your main forces from the armored troops eastward.Finally,send most of them to take the last two cities(In my case,I left Model to defend the armored forces while sending only Rommel and Bock to take the last two cities,due to how incompetent Messe was,I had to send Model and a near-death light artillery to take the north city).Also, its important to take the airports to take out the enemy with your mass economy.
Note:This is not the only way to finish this mission since my generals only consists of the free ones and Rommel

Yes you can. Use predesignated generals for that mission and kill enemies and you farm medals. Longer mission and more enemies the better.
