Artillery/mortar not working

[kexxey]

Hello, I bought Men of War package on Steam a while ago, and I enjoy the game but I seem to be unable to get artillery to work.. And the missions in red tide is just impossible to do without artillery.. Ive tried making them attack ground and infantry/vehicle targets and they just dont want to fire :S
If i aim at tank, they change to AP and if infantry HE, and i cannot figure out how to make them fire... And yes they do have ammo and a two person crew.
Help please!

Regards,
Kexxey.
