I have played this damn mission for over 10 hours now over the last 3-4 days and still can not beat it.
I started not even bothering with the little missions and go straight for the base. Arty'd it one time to take out the tank. Boomerang finally shows up, but all they do it go straight into the line of fire of the BMP which takes out the APC with one shot. I've tried going in on foot and also with the APC. One shot from the BMP every time and we blow up.
This is ridiculous that this mission takes up so much time and have so many failures with the design of the mission. I've simply had it with this game. It looked so promising and the previous missions and training were a lot of fun, but this mission sucked all that fun out of the game. Unless I see a patch within a week that fixes this crap, it will be time to uninstall the game and fight for my money back.
