Cannot Complete Mission

[kermitbuns]

Hello,
I get to Mission 4 in DOW where i'm supposed to use the artillery on the hill to take out the camp below me. For some reason, when I use the attack ground, or the simple attack command the tanks roll up to the side but do not fire. The reload indicator keeps filling 1/4 the way up then starts over. I've tried everything i can possibly think of but they dont' work and I can't beat that mission without them. Please help.

We get this question every week, probably because people don't use the search function. Anyways you have to change their stance, by default they are set to 'cease fire' (otherwise they'd end up shooting that ork encampment during the cutscene).
