"On-map" or "off" ?

[Colonel Talvela]

Personally, I think that on-map mortars teams are probably the most valuable units in the game - other than inf squads of course. And, for me, it is hard to get comparable results with off-map artillery/mortars.

Off-map will have a bigger area of affect certainly. But there is usually a certain spot on the map that I need precision fire to, and off-map is much better for that.
