Some thoughts on the front line:
. The bigger the front line, the more visible the problem will be. Thus, the problem will be seen more in Russia than on a reduced front like Poland or France.
. The human thinks vitally to its flanks for what reason? In order not to lose his life line, understand his line of refueling. For AI, this must result in attacks that follow the lines of communication, roads / railroads to maximize refueling. And, a use of all units to, with the ZOC, prevent incursions behind the front line thus secure flanks.
. On a broad front, this means dividing one corps into division to cover a wider area (1).
That it is necessary to give ground to put ourselves in better situation if need (2). Too advanced and it is death assured.
That there is a need to reduce salients if it reduces the number of units on the front line (3).
Is the AI able to do the three above algorithms (1) (2) (3) when planning its offensive or defensive move?
I know this will considerably lengthen the time of reflection of the AI and thus the passage to the next turn. So, it's a design choice.
But it's worth the wait if it prevents the AI from leaving holes in its front line.
