This looks very interesting. May I ask how you will only control the afrikakorps? I know how to make the ai control production and stuff. But how will you do it for all the other military units Germany controls?
You can put any theatre under AI control of a theatre commander (usually a field Marshall). For example, in the 1939 campaign as Grmany, the Western Front theatre can be put under control of FM Kesselring, so all other HQs in that theatre (Rommel, Manstein etc) are under his command. It is important in such a case to verify that the sub-HQs are effectively under the command of the theatre commander, otherwise they will need to be given orders by you.
If you want to give orders to any of the sub-commanders, then you must not put the theatre commander under AI control, or you must detach the sub-commander from the theatre commander (in which case they lose the bonus of the theatre commander). This would not be a problem in Afrika because of the small number of commanders.
For example in the 1939 CG as the Germans, I put the Western front under AI theatre commander Kesselring who already had all the other HQs under him, giving him total control of the theatre, and put his stance under defence so that he would react to any French incursions.
Then for Poland AG South and AG North are both under OKH, but none of them have commanders because there are no Field Marshalls available, so I promoted 3 and put them in charge of OKH, AG North and AG South. Here you have 4 possibilities for AI control: 1)You can put the whole shebang under OKH (this does not iclude the air forces unless you change them) and watch the AI fight for Poland, or 2) put both AG South and AG North under AI control with different orders (probably Blitkzing to Lotz and Warsaw and maybe Danzig) and watch or maybe control the Air forces,or 3) put some of the Corps HQs under AI control and control others yourself, or 4) put everything under OKH as in (1), and detach some HQs (either an AG or a Corps) so you can control it yourself. For example if you use option (1), the AI may not go after Danzig and you may have to detach a Corps to go after it.
The important point is that if you put a HQ under AI control, all its sub-HQs are under AI control too, unless you detach them and lose the superior HQ bonus. IMO this should be changed and one should be allowed to give specific orders to a sub-HQ under an AI superior HQ without losing the bonus.
So inpractice you may want to avoid putting a Theater HQ under AI control except when that theatre is not critical (such as the French border in 1939).
