Who has to be in open terrain for HI to get +2 (per p 14)?

1. The HI has to be in open terrain?
2. The LMI has to be in open terrain?
3. Both have to be in open terrain?

Good question! No, page 64 is not that useful.
By analogy, "open" terrain is penalizing for LMI _when they match up with HI_. By analogy, then any part of the LMI base in open will grant the HI the +2. Furthermore, by analogy if the LMI is right at the edge of rough or difficult, and attack HI in open, then HI also benefit.
But that's a lot of analogy.

(Ok, I made a quick check of the errata - I think MAM is recalling the ruling about when LI must evade. That takes into account the "fighting edge". That's not a bad way of adjudicating this.)

And then there's the question of LMI emerging from Woods and attacked by HI. Is the HI +2 and the LMI -1 (for penalizing difficult), or is it one or the other but not both?

This applies to LH fighting LI, too.

I have always played that it is pretty simple, and based on any part of the base for the unit in question rather than fighting edge.

Any part of base in terrain take the minus, so LMI -1 with rear edge in difficult
No part of base in terrain no minus, so heavy foot +2, in open.

Ps ref comment on lining the edge. It is geometrically possible for a straight edges base to line the edge of straight edge featues (fields, plantation, built up areas), but not any others as they are irregular.

I do feel reading the rules will identify the answer here. Thst includes combats on the edge of terrain. (Treated as in terrain)
