According to the 2D10 combat table in its 4th point when the factors of the attacking units are halved the attacking bonuses are also halved. So far so good.
1.The problem arises when we need to consider what is an attacking bonus. It seems clear that a blitz bonus its an attacking bonus but what happens when a unit is face down (+2 modifier)? Is it an attacking bonus?
2. Let´s assume that it is an attacking bonus. What would happen if some units are attacking across river (so attacking factor being halved) and other units are attacking through clear terrain (attacking factors not halved)? Are the bounuses halved or they aren´t?
I hope I made myself clear. Thanks for your replies.
