[Mobhack]

IIRC, setting the range with the Y key was always per-unit in the original SSI code,

What I added was the selection of specific hexes in a list, or choose to put in a typed range which I think was the original method SSI used -- its 20 odd years ago.

I also added the Formation option, so you can do things a platoon at a time Y-F-range and all 4 or 6 or whatever elements have the same range set.
