Over the years, I've come up with a few of my own home grown house rules. First I have a chart of house rules units, and then a document I created not too long ago with rules for different kinds of units and national house rules.

My House Rules

The next house rules document is for my own set of Air Units Rules. I didn't like the air pack rules, when it came out. I thought that if a tank moved about 24 to 40 miles per hour, and went three spaces in a turn, an airplane flying overhead at about 440 miles per hour, the airplane would be able to move across the whole battlefield in less time than it takes the tank to move it's three spaces. So in my rules, the air unit is placed anywhere in a legal full hex on the board, and then makes it's attack.
