A couple of things to take into consideration for planning:
4/42: you get a bump to all armies and front capacities: (army goes from 24 to 27 and front goes from 72 to 81).
Remember that when you form infantry corps, 3 infantry divisions (6 points) OR 2 infantry divisions and 1 brigade (5 points) becomes a infantry corps (4 points).
And I have found a rather powerful defensive/offensive carpet to be
1. Army four hex front
Front line four inf corps in first rank
Support line two inf corps in "Reserve" in second rank with three tank brigades (for greater depth put tank brigades in two line with gaps and the Reserve infantry corps behind them
2.THREE armies per Front
3. One "Filler" STAVKA army (if needed) with 27 points of NON-CORPS units between each Front (in some cases the Filler army may form a third line behind Front)
4. One-two "Builder" STAVKA armies in checkerboard behind front building forts
Until there are sufficient infantry corps, use inf div stacks- two high or three high depending upon need for frontline versus support line strength
This structure allows an Army depth of up to four hexes for flexible defense or a four corps, two brigade attack on a two hex front (while maintaining two corps as flank protection). The tank brigades also are excellent for exploiting counter-attacks on the flanks of breakthroughs. The "Builder" army behint the Front armies can also add another four-six hexes of checkerboard divisions to the defensive depth. Note that this structure does NOT overload either a Front or Army
Just a thought although it is usually 43 before this can be implemented across the entire front
