I myself do the following:
- Starting pios go cap right away, preferably a fuel point
- build mg42 right away, moves up to captured fuel
- build another mg 42 and set it up so it covers the first
- 2nd pio squad that goes capping as well
- 1st battlephase asap
- t2 asap
- either 2 panzergrenadiers followed by pak 40 or 1 panzergrenadier followed by pak 40 followed by panzergrenadier
from there I go to t3 and spam p4s and add some paks in there if I need it.
Works vs Soviets and USF. Although it will mean you have less of the map in the beginning, but you can get away with camping, especially if you face USF, since they pretty much have lost the game if they haven't overwhelmed you at the 10-12 minute mark.
Have tested it many times and it works 95% of the time. People just don't expect it, and will try to dislodge you of your secure little sector. With the 2mgs and your pios and panzergrenadiers you can bleed them dry. If you face USF, you can bleed them so well that you can then go and cap pretty much uncontested for some time.
Soviets will usually throw m5 quad at you, which your pak 40 can counter since he has to attack your smaller area. USF will either go m20, which will fail horribly vs pak 40 and a small held area, or they go stuart, which will have to be very careful vs your pak 40 and you can usually kill because they rush it in.
From there get p4 and add what you need, preferably more p4s
It even works on Stalingrad \

EDIT:
Commanders that work well with this is any commander that has spotting scopes, preferably Elephant commander. Works very need in Minsk Pocket!
Also, The Mechanized Assault with a lovely Stug E complements this strategy very well!
