Range of fire for on map artillery division

[Weasel]

Wouldn't it be nice if they rewrote the manual:

Heavy Artillery: has a X% chance of reducing fortifications
Motorcycle regiment: provides X% to detection level of enemy forces and reduces enemy detection level of your forces by X%.

I also have to search to try and find out which units can be attached to Soviet corps, right now it seems engineers, tanks, FT units and mg-arty battalion but not mortar or rocket units; but I have to check more.

I didn't see that post but it is great information; maybe I will try MORE arty divisions then.
