1) Jap AI air power never used en masse, only piecemeal;
2) Jap AI air used often against Victoria Island, but not against coastal artillery there;
3) still no serious land attacks by the Jap AI, to drive down the roads
a) use four or more air units to support a single land attack every turn, for instance to help drive down the roads
b) use 3+ air units together every turn to attack one coastal artillery installation
When I've played the Japanese side, I have been unable to have land attack success much without air support. Is the AI smart enough to look ahead, see which region it is attacking by land, and add air support to that region?
