finally managed to polish this off last night on normal. the first few check points on the last level drove me MAD!
theres 3 armor units that need to be destroyed - you start with a Javelin which easily takes out the 1st tank, then in an ammo crate you can switch the empty Javelin with a Queen Bee to destroy the to AA vehicles in the small village but OVER and OVER again they just failed to destroy the two AA's and time is a factor as you cant let them shoot down the allied helos - after MANY restarts of rushing the that point i finally came across another ammo crate in one of the houses with another stash of Queen Bee ammo to destroy the seemingly indestructible tanks and head down to the naval yard in a transport helo which was alot of fun.
im going to and go though it again on hardcore when the allied AI patch and ballistics is fixed in an apparent upcoming patch because i dont think i have the patience to try it right now.
all in all - apart from the AI issue i loved it!
