Sighting Question

[Walrus]

Which game platform are you playing?
WW2 / MBT (SPCAMO) or some WAW version?

Sometimes in SPCAMO versions, it is possible to see one way through some obstruction (trees usually) due to the distance from the object, however your explanation makes me wonder what is happening.
Was there any smoke involved?

Was it indirect fire that you were getting hit by? Fire using the 'z' key.
You can tell when it is that as the script at the top left of the screen (I think that's where it is) will show the enemy fire targeting a hex, rather than your vehicle.

Maybe someone else can help...most interesting.
If it's not one of the above, I am stumped.

Good luck
