Different LOS in set up and actual game

[Rico]

Has anyone else had this problem.

In two games now, I place an AT gun or Heavy MG into a position during the set up zone and check LOS and it has good field of fire.

Once the actual battle starts, suddenly most of the original field of fire is suddenly out of LOS ... how is that possible?

AFAIK this can have two reasons.
First: You checked LOS during setup with troops not hiding (the only way to do this ). If you hide them after checking LOS for the start of the game they hit the ground and maybe loose LOS. But this shoudl be no problem as if you unhide them they should be in LOS again.
Second: You checked LOS and applied a covered target arc after that. This will sometimes have them look or position slightly different than intended. What I do in this case is set them up, give them a direction command, check LOS. Try a bit with different direction (as LOS and position of the gun and crew may change) until you have LOS to the desired area. Then just hide them without a covered arc as this causes them often to reposition or turn the gun in another direction. Apply planned covered arcs after turn 1 and they should stay where they are. This works for me most of the time. And I don`t trust LOS always. I get down to level 1 have a look for my self with lots of zooming in on the target area. If I can see it I can hit it regardless what the LOS tool states. At least it works most of the time ;-)
