Whirlwinds not firing

[Ham]

I am on that mission in campaign where you start off with 3 whirlwinds and 2 squads of assault marines, with the ork base below. I tried to attack ground with my whirlwinds and they just move to that location instead of firing on it.


I have version 1.40

Change their attack stance to attack and they will automatically attack.
