LOS on page 23 4th Edition Rules. (F - G)

[tlangston28]

....

What about G-H ? I think it's blocked ... funny they don't assess it....

I think the rule here is that both units are the same distance from the elevation line so LOS not blocked.  If the unit in G was in 1108, then yes I would say that LOS is blocked.

Under this verbage (pg 22, 8.42 second bullet):

* One or more slope hexes of the same elevation as the higher unit lies between the two hexes and the slope hex is closer (not equidistant) to the lower unit than the higher one. 

Both units are adjacent to the slope hex which means they are equidistant from the slope hex.

That's my take anyway.
