I am currently loving Royal Artillery. Mortar spam until the Priests arrive seems to work against Expert AI pretty well, anyway.
Oke, anything spam works well against the Expert AI. Matter of fact, i can't tell the difference between the Normal AI the the Expert AI. Hell i once held of a Brit Expert AI with just a double schreked Gren squad and a sniper! I didn't even choose a doctrine in the whole game of 20mins either.
I didn't make it!
Yep expert AI is not a chalange at all, I once locked one down in his base and the only thing he did was suisiding calliopes into my flaks and paks range to barrage my HQ. So many wrecks... :(
