Turn 39- I brought in some air power as you suggested,and for the most part it was effective. However I have made some mistakes that
have cost me the loss of USMC units. Forgetting about certain things for example and then enemy arty is raining on it.

A direct hit sunk one of the barges.

Maybe I'm just going to fast,but I wanted to test as much as possible.
On the other hand I am on Chinese territory,so a price would be paid by any invader. I'll have to postpone any further testing,as I have to move in a week,and at this point there is no destination.
The map is nice but seems like could use a little work,where some hexes are not correct.
The screen shot shows the PRC tank graveyard SW corner of city,and of course the latest save game.
