Build MG, then Mortar in the beginning. Followed by a 2nd pio. Start capping like normal, but don't get worked up over one flag if the enemy is being persistent. The mortar tends to discourage all out assaults. Start building fuel caches rapidly once your infantry has been built. You should have one or two by the time you hit to go to tier 1. Play it safe with your infantry and do be too brave. The main part of this strategy is being conservative with inf. so you can jump to armor rapidly. When you hit tier 1 build the new building for P.grenz if clown cars a problem, if not you should have enough to go straight to tier 2. At this point it is safe to add a couple of grenadier regiments. Keep building fuel caches... Once you hit tier 2 build an armor korps and start rolling out the PzIVs. The enemy may have an AT gun at this point, but not much more. Play it safe with the Pz and keep focusing on building more. Having 4 pios when it is all said and done is very helpful too since you can rapidly repair your armor. Since there is little that can damage your PzIV's early on they can easily level up, as well as flush out any soviet armor that has been getting stock piled in their base, averting problems down the road. This strategy has worked really well when running Jaeger armor because by the time the enemy has started getting more than one heavy tank, you should have enough for the elefant.
