Well thats the thing I have yet to have a Mule, tank and crew all at the same time. the hardest I have had for multiple commands has been crew, helicopter and tank but it was actually really simple to do.

The tank moved in sections so as we moved forward two sections you command the tank forward one. The helicopter was only used for two strikes. Your unit is intelligent and you put them in the basic vacinity and put them on kill at will.

I dunno playing the demo I have noticed is rarely a fair shake of the game as an overall.
