[Rules] [Terrain in Beyond Normandy & War in the Hedgerows: Operation Epsom, 1944

[broadsword]

The Campaigns & Commanders book, "The King's Officers" has several pages of terrain rules that bring PG Beyond Normandy into synch with the PG 3rd Edition ruleset.

A lot of these rules are helpful clarifications, while others (like eliminating formation morale) simplify and streamline PGBN.

The one I keep having some trouble wrapping my head around is a really basic and important rule: Hills.

Beyond Normandy is a "real terrain" map, unlike many other PG games.

The Campaigns & Commanders book states:
"Hill: See TEC. Note that there are no Clear hexes on the Beyond Normandy maps; all hexes are Hill hexes because they are above 20 meters in elevation.
Many Hill hexes have other terrain in them as well, and all terrain effects are cumulative. Note also that while Hill hexes are limiting terrain (8.2) they do not block LOS all by themselves; elevation lines block LOS per rule 8.4, and other terrain in a hill hex can block LOS per the TEC and the rules below."

I'm trying to nail down how this affects movement.

In the basic PG Terrain Effects Chart, a Hill hex is +1/+5/+3.
But in Beyond Normandy scenario rules, The Hill terrain has no MP cost of its own and the chart says to use only the effects of whatever other terrain might be in the hex.

So, I've been playing Hill (which is every hex on the board in Beyond Normandy) = 0 MP cost, but adding MP costs for other terrain in it, and for any scenario or campaign/specific rules. For example, the first day of the War In the Hedgerows campaign has Light Rain weather conditions, and that means +2 MP for all vehicles to enter any non-road hex.

Question: Is there also any MP cost for crossing an elevation line "uphill" in Beyond Normandy? If everything is on a slope of some sort, I wouldn't see why. But I'm wondering if I'm missing a terrain cost.

Also: In Beyond Normandy, each elevation level adds 6 hexes of LOS distance. The current weather in effect says the maximum visibility is 12 hexes. So, how do I reconcile elevation vs. weather? Is the weather limit a firm, absolute number of hexes one can see, no matter what the elevation? That's how I play it, so the elevation bonus for LOS is always "weather pemitting." Makes sense in the real world. Just want to see if this is correct.
