The differences are mostly minor, mostly longer turn counts. Scenarios 36 & 37 switched from Imperial Army to Imperial Navy.

A heads up on scenarios 19 to 23, USMC HMG's are really WPN's. (Most players should figure that out.)

It's weird how the 3rd Ind Mtn Artillery Regiment has none of its 75mm howitzers.
