I think it might also have to do with the additional rules/exceptions not found in other AA games such as CAPS, airfields, naval bases, Japan’s first round attack on US forces (defending at 1).
According to the user manual Allied units (both Commonwealth and Us forces,…not only Us forces) may defend only with a roll of 1. Of course, any attacks made in Chinese territory are defended by rolling at full strength.
Thanks for the links, Flashman. They look like they will be very helpful. I suspect that I might still make up my own set of rules, but they give plenty of starting points.
Chinese and Indian Infantry would just stack up while you wasted everyone of your fighters…then the U.S. would just come in from your rear and wipe you up.
