Barring other terrain features, two units at the same level, and on the same hill, are not in limiting terrain with respect to each other. LOS between these units is limited normally by terrain and visibility. Units at the same level do not receive the -1 DF column shift for firing at each other.

I don't agree with this. There are many long hills in PG but they are still hill that have a shape from which units can use to hide in.
