One for appraisal.

The enemy unit is one hex back from an elevation marker and a friendly unit is off the elevation hex in a defilade. My opponent believes his unit can see down in the defilade, while I don't believe so. (Situationally: Map 77:  Hex 1007 - enemy unit, Hex 1107 - elevation hex, Hex 1206 - friendly unit) So who is the correct one?

My take is: if there is a single slope hex containing a contour line between the upper, firing unit and the lower, target unit, both units can see and fire at each other.

[Tankodactyl]

Concur with ACav's formula.

If the two units are equidistant for each other with a slope contour hex in between -- they can see and fire on each other.

[Grognard Gunny]

So let it be written, so let it be done. (Then there is relatively NO slope that blocks..... that makes the problems MUCH more "interesting", yes?)

....and taking it a step further, The friendly unit could be ANY NUMBER of hexes away from the "edge" of the hill mass and still see. yes?

I am not sure I understand the question, but feels like a no.

There are a few. The rules says LOS is blocked if the lower unit is closer to the elevation line than the higher unit. So, if unit A is 1 hex from the elevation line and lower, and unit B is at higher elevation and 2 hexes away, the units cannot see each other. In your first example that would be like having units in hexes 0908 and 1206.

NO.

See 8.42

8.42LOS is BLOCKED if both the spotting and target hex are on DIFFERENT elevations, and:

• one or more slope hexes of higher elevation than the higher unit lies between the two hexes;
  
• 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;
  
• a limiting terrain hex that blocks LOS (for example, town or woods), that is higher elevation than the higher unit, lies between the two hexes;
  
• a limiting terrain hex that blocks LOS (for example, town　or woods), of the same elevation as the higher unit, lies　between the two hexes and the limiting terrain hex is closer　(not equidistant) to the lower unit than the higher one.

I got all the spotting "influences" down except the one I noted. Perhaps the map designers should not draw in elevation topographical "stuff" where it does not exist. I, for instance, assume that there is a "military crest" along topographical highlights. Hence, my dismay at getting my butt shot off when I fully believe that I am in a defile. Apparently not. A simple elevation line, as drawn, without the additional "stuff" drawn in should be sufficient.

Whew, beware of becoming a rules lawyer, my friend.

My rule of thumb is:
You own the game, play it the way you want in solitaire, and discuss/decide how you and your opponent want to play when you're in face-to-face, or online in shared encounters.

Shared play makes this fiddly kid's game much more fun to spend time playing.
