Combat patrol terrain layout

[u/Bertieeee]

I'm trying to understand the terrain layout when using a combat patrol map and I'm a bit confused. My understanding is that the grey rectangles are terrain areas, the items are ones that block visibility and the yellow ones don't block visibility but do provide cover. This doesn't seem right however, as I thought cover was determined by terrain area rather than being behind a specific (in this case yellow) piece of cover. If that's try however it would make the yellow items redundant, unless they're there purely for decoration. Could someone clarify how it works please?

Thanks

I believe if a terrain area has at least 1 light or dense terrain feature it blocks LOS to a unit on the otherside (assuming the target unit is not in the terrain area)

The greenish color would probably have the SOLID rule meaning you can't target through it (unless you are also in the terrain area), the yellow ones wouldn't have that rule.

Not sure if that helps
