I have been watching some videos on open battle fighting. I came up with an idea that if two or more inf. units are standing shoulder to shoulder and at full 4 figures, and on open ground, that they get i more dice to roll . This would only be good as lone as each unit stays at full 4 figures. Units that lose 1 figure or who get a flag, do not get the extra dice. I tried this as a house rule and liked it . Please let me know what you think of it.
