An example of my last test of this situation

This is start of Turn 4 on board 2.

Germans have now reached the mine fields. No casualties yet on either side!

Units highlighted in purple have been just "Disrupted" by Russian fire (better than dispersed).

Note that I have magnified the board to allow more units to be placed on an hex. without physically stacking them.

Improved Combat Table

This combat table was the result of my frustration in seeing so many attacks with the same odds against the same target even though the attacker's AF could be quite different (often nearly strong enough for the next up ratio).
So, I thought of inserting "half" ratios.
This really does affect the game positively and increases the attacking value of weaker units, as it must be the case in real battles.
