My 2 cents worth regarding Africa.
I would be carefull regarding the use of the Italian fighter - the reason for this is that it usually comes of allot worse versus the better tech UK fighter groups and this results in a pip drain for the poor italians.
I would remove the Italian fighter and replace this with a german one and use the Italian on the russian front where it has parity in tech (ie very little) at least.
The other point - as has been demonstrated many times before - Italians alone struggle to take Africa - I can see some germans on there way but dont go too early without there support or you could find yourself in a fighting retreat without rommel.
Please use my advice sparingly as I am by no means an expert - I have just lost enough to realise a few of my mistakes
