Yeah, the way I see it, I gotta use my army to stop his. If he wants to send in another 6000 AV, I will too. But if he dosen't, I've got to keep mine on alert for more invasions.
I'm curious how 12,000 AV vs. 12,000 AV would fare in the open. Probably really bloody on both sides [:D] He's going to have tank superiority, but I've got forts and will have lots of AT guns there.
Yes, you have to be on defensive. I recall in original WITP, my opponent tried invasion of Marians but we ended in situation like this one. He was even unable to supply his units propertly, so after i month ive tried with attack [:D]
gosh, that was such a bad idea. I didnt get even close to 1:1 and lost 2 dozens of thousands men. All that because a stupid design "soldiers can hold tones of supply in their pockets" (and there is no way to destroy it) - actually im pretty sure that is not changed in Allied Edition, right Castor Troy?

So all you have to do is keep blocking his troops, and do not overcrowd base - keep rotate divisions from rear and invaded base (im sure he will start with air attacks on your ground units there).
Use your subs for some minelaying there, send MTBs there.
It looks his armored units suffered a lot (quite a lot destroyed vech's , it will take a while until they regain strength i guess).
You have lvl 9 forts there, right?
