your frontline from Riga southwards on the river looks pretty good! I think you should put the units which are facing the enemy into static mode. In static mode their attriction losses are much lower. This will help to stabilize your manpower. I would set as much units as possible into static mode ... everywhere where the frontline is stable and the Sovjets are not attacking. It seems you have a lot of APs, so you can reactive masses of static units if necessary.
I would also search for units to disband ... security divs, useless SU (e.g. SIG 33 SpGun). SUs are always handled in refit mode, so maybe it's good to reduce their max TOE (e.g. AA ...) to ensure that more manpower is sent to your inf divs.
You will lose the game much faster if you stop attacking. So sent as much forces as possible to the south (it seems there is the most action) and attack like crazy. Maybe some kind of "backhand blow"? Fall back 2-3 hexes in clear terrain and if he follows you push him back or encircle him.
Ah yes, did not consider static mode, thanks for the heads up.
For the time being, the security divisions are used to dig, they do not do so very well, but every little bit helps, but I guess I could indeed disband some SUs.
As to attacking, I do attack as much as possible, but the problem is that only a handful of units are capable of attacking and succeeding at this time, and I need to watch my offensive capabilities so that I do not "spend" them on useless attacks, as these handful of units are my only choice to deal with breakthroughs from the USSR. That being said, almost all attacks I make are in the south against an ocean of USSR Guards units, and I usually force 4-5 stacks to fall back every turn. The idea of a backhand blow is a good one, but one that will see my fortified frontline destroyed, so I am afraid to move untill I have a proper fallback line behind me in case I cannot retain the USSR troops as soon as I move from my forts.
