Height of Bocage/Hedges/Hedgerows final ruling

[Blackcloud6]

Looking at the rules today for another case, I reread this:

8.32 Terrain that Blocks LOSThe TEC specifies which terrain features are tall enough to block LOS due to vegetation, buildings or other obstructions for a spotter and target on the same level. For game LOS purposes, they are assumed to be 20 meters in elevation in addition to the elevation of the land upon which they sit.

So, there is no question that the hedges/bocage etc. are 20 meters tall for game purposes.  Since hey block LOS beyond the hex, they are 20 meters tall.  Railroad embankments are the same.
