Japanese Hard Attack Values in PzC

[Steel God]

Playing P44 for the first time and I'm struck by the HA values for the Japanese regular infantry units (8).  Okay the range is 0 but still that's 4x greater than actual IJA Armor units.  The AF Battalions, which one assumes are not exactly trained to be ground troops as a primary role, have a HA value of 6.  Without going to check I'm thinking there are no European Armies in PzC that have any regular infantry units with a HA of 8, and those armies had all manner of personal AT weapons available to them by 1944.  I've gone through the designer notes hoping to find some explanation of actual design decisions, but for better or worse the notes are actually just 160 pages of history and not really notes that document the design decisions of the game in development  So my question is, does anyone know why the HA values for Japanese units were set the way they were?  What does that represent?  As I don't own either of the Japan titles, are the HA values in those games also set at 8?
