It's the German Defensive Fire Segment of turn 7/7 in Training Scenario 1, and while trying to fire the HS and the LMG in hex 2,14, I get the message displayed in the pic below.
Why in the world can't I fire the HS and LMG together?
The LMG is in working order (it's just been repaired in the Administrative Segment), it's possessed, and I can fire the Leader together with the LMG, the Leader with the HS, the HS alone, but I can't fire the LMG if I add the HS to the fire group.
It's driving me crazy. What am I missing here?
Many thanks for your help.
