Anyone else having trouble with LOS

[A Canadian Cat]

I strongly suspect, same as raz_atoth, that your tiger does not have LOF to the target. That symptom of the gunner aiming, spotting is a strong indication of that. The way the game works each crewman spots on their own. It is not uncommon for the TC - who usually has the highest vantage point - can see something the gunner cannot fire at.

The solution is to jockey your tanks position such that it improves its vantage point. Perhaps a bit forward on a hill to get higher, perhaps back up an forward slightly to one side to get away from a tree that is blocking. I find that getting down at gun height and turning on trees helps figure out what my guys are going to be able to fire at.

Here is a little video tutorial I put together showing how I check visibility: https://www.youtube.com/watch?v=M6IhU2frfmE

When I say visibility I mean LOF.
