This is Battleground Italy, which I've now got some experience with.
First off we check the weather, which is excellent:

For the air war I'm going to focus my strategic assets on just the railyards this time. Last time I split targets with ports to try and slow supply that way, but I want more results over railyards this time to try and limit his strategic movement in response to my invasion.


On the ground in Sicily I'm going to try and go with as few reinforcements as possible. My goal is to get 5th Army prepped and invading The Heel as soon as August arrives. I could invade even sooner, but I want all the surrender checks in operation when I make my invasion of the Italian mainland.
7th Army will pull from Sicily as soon as the western airbases and Palermo are secured. 7th Army will be responsible for the armor on the Mainland. 8th Army will be responsible for holding German attention in Sicily, and then mopping up.
The Americans and British concentrate their forces on battering the Italians, hoping to shatter and route as many units as possible to prevent any forward defense in the hills. Patton's 2nd Armored Division is successful in getting around the Axis flank while 8th Army clears everything in the east south of Catania.

Lastly I relocate some Spitfire (and Kittyhawk) squadrons to start fleshing out the Sicilian airbases. This game I learned some more about the Air Support replacement flow, and hope to share what I've gathered.

First: I'm going to try and make most of the air bases on Sicily USA owned so that they can draw from the superior American manpower pool. I made a mistake in putting the airbases at 99% Max TOE, because as Helpless explained in my war room thread the way the replacement code functions for specified Max TOE is it pulls enough to meet the need, or it pulls NOTHING. The manual suggests a setting of '55', but without explaining the 'all or nothing' nature of the replacement function you're left guessing why that matters. By just putting in a squadron or two you should be able to make a successful pull on the manpower pool, but beware trying to fill too many airbases at once, even if you are trying to take it in small doses. Even with huge amounts in the manpower pool and Air Support pool I had airbases later on get nothing. I think I may have been hitting a replacement threshold for that area??? Not really sure, just trying to find out what works, and why.
