I think your approach is the right one in general terms. The wooded right side and the two sides off the road are the "entry... Yesterday, I achieved a Total Victory - with russian surrendering and my guys already beyond the Church... Altough this result is rare, a "Major" it's easy to get.
But you have to "cheat" the AI deploy wich I believe sort of responds simmetricaly to yours, at least in the "Free to Place Units" mode.
If you deploy the pioneers more to the center the AI will spread more it's defense. And this is the key. Four pioneer squads can (by the 3rd play) run and enter the attack corridor.
By the same reasons you must place the vehicules at the center - they can advance slowly after like a trident, and after you get read of AT guns, charge the buildings.
The recon platoon (plus HMG) on the left contributes for the covering fire and - once your attack force is inside the trench and the houses on the right side of the road - they can even charge the trench, get there and go as far as the Church or more!
Fundamental is your field gun, that must be deployed in such a way that allows it to fire all the first line of buildings -even the two heavy ones on the left - and, eventually smoke the advance of your first attack group (the recons with the "stealth officer. Theese guys can even "move" half the way trough the "bushes" and hide, before they advance after your gun, vheicules and other forces have harassed russian defenses to the left. The "smoke" of blown up houses offers good cover to your assault to the "woods"...
Try a couple of times - there are some small details you must analise - and believe me. It can be easyly done gainst the machine.
I confess I would like to play this one against a human player. Maybe I am wrong but I think that in this case the russian position is not conquerable.
