I'm talking about the automatic support level, which is set to 3 for every single HQ at the start of the game, irrespective of corps size, role or location. If this is not a problem, why is the Boot Camp recommending players to go through each of their HQs to change it?
This is what it says:
We discovered many schools of thought when testing a) set O.K.H Support Level to 1, AGN to 2, each attached Army HQ to 3 and then each Corps HQ to 4 or more depending on the number of divisions within that HQ or b) set each HQ to 3 or c) Set the Higher HQ to 9 and then all of the HQ in the chain of command downwards to 0. What this will do is transfer back up the chain of command all those support units to higher HQ and then you can the following turns reset the support level to bring in the support units you want.
But he then goes on to advocate a modified version of a), in which the support level is set at the number of corps/divisions under the HQ's control, although sometimes one higher for important spearhead units:
Now go ahead and click the X to close out this window, this will take you back to AGN, go ahead and click on the 18th Army text. Same thing here lets set our support level to 4 this time though since we have four corps HQs.
~ 34 ~
When you're done go ahead and click the X and then when you're in the AGN unit detail window go ahead and click on the 4th Panzer Group text to get to the 4th Panzer Group HQ unit detail window. You'll see you have only two panzer corps and an army level attached unit (the Totenkopf SS Motorized division). Since this is one of the spearheads go ahead and increase the support level to 3
Now let's click on the XXXXI Panzer Corps HQ text. Again, this will bring us directly to the XXXXI Panzer Corps HQ unit detail window.
~ 36 ~
Now we're getting to some of the meat on the bones here. Take a look at this unit detail screen, the attached units are the 1st and 6th Panzer Division, the 36th Motorized Division and the 269th Infantry Divisions.
Go ahead and set the support level to 4 for the XXXXI Panzer Corps (my preference really since there is 4 divisions that could have up to three support units attached), when done click the X which will take you back to the 4th Panzer Group now go ahead and click on the LVI Panzer Corps and go ahead and set the support level to 3 for this HQ.
Note that all this clicking and viewing and resetting of support levels is stuff that is being recommended before you have even moved a single unit.
So it is of some importance to players, especially new or novice ones, whether any of this laborious tinkering with the at-start HQ support levels is actually rationally based.
In a Grand Campaign, there are more than 100 German HQs that supposedly require checking in this manner at game start.
I have so far found only one scenario (Kharkov 42), in which the support level is not set at 3 for every HQ. The designer of that particular scenario presumably thought there was something wrong with "one size fits all", yet this is how it is in the other scenarios.
