All good questions.
Here are important supply considerations:
HQs use the trucks in the Motor Pool to move their supply dumps. Thus, HQs with a lot of dumps can become problematic detractors from supply elsewhere. Try not to move HQs far if they have a lot of dumps. But generally as the German, your Panzer corps' dump number is usually decently small.
Aerial resupply works well to a panzer corps HQ rather than flying missions to each separate division. As long as the combat units are within 5 hexes/20 MP, you can consider going straight to the HQ with air supply. I sometimes do it directly to divisions if I need that specific unit to have higher MP.
TIP: When flying air supply to an HQ, if that HQ is stacked with other units, the dropped supply/fuel will be shared, and often the unit will take more of the dropped supply than the HQ. To avoid this, when moving your HQs, move the HQ to a hex 1-hex away from its final destination so it's stacked alone. THEN fly air supply. Then move the HQ onto the unit that will protect it. Ensures the HQ gets all its supply itself, and minimizes truck usage only having to move those dumps 1 hex.
HQs draw extra supply (i.e., more than they otherwise would) if ANY of the following conditions apply:
a) The HQ has more than 50% of its vehicle Need
b) The motor pool has a vehicle surplus
c) The HQ is within 10 hexes of a railhead
Tip: If your HQ has fewer than 50% of its vehicle need, try to keep it within 10 hexes of (next turn's) railhead.
Try very hard not to strain your motor pool. This is best achieved by careful movement of units, especially HQs. Use rail and naval whenever possible. Every truck counts! Move air bases efficiently. Move higher level HQs the minimum distance to stay within 15 (or whatever) hexes of the farthest subordinate.
Tip: Consider carefully whether you need to advance a unit greater than 15 hexes from a railhead (10 hexes for the HQ to railhead, 5 hexes from the unit to HQ). Plan rail repair accordingly. Keeping my infantry HQs 10 hexes from railhead and my infantry 5 hexes from the HQ has resulted in me having an average of 14 for my infantry movement each turn. This REALLY helps supply, but is admittedly not always possible for panzer corps and units.
Supply delivery modifiers for ALL units (including airbases, HQs, and units):
Supply delivery to any unit is modified as follows:
Distance to railhead from unit is less than or equal to 25 MP, unit receives full supply (this is not to say 100% of need, because fatigue and experience play a part that is not defined).
When distance to railhead is greater than 25, supply is modified (reduced) by a percentage equal to the following:
25/actual distance in MPs.
For example, if you were 50 MPs away from the railhead, your supply delivery in tons would be multiplied by 0.5, and thus, half your supply amount would not be delivered.
Another, CUMULATIVE, modifier exists for the number of hexes to railhead, as follows:
When hexes to railhead is less than or equal to 10, full supply arrives.
When hexes to railhead is greater than 10, supply is modified (reduced) by a percentage equal to the following:
10/actual hexes to railhead
Again, if you're 20 hexes from railhead, your supply received will be reduced by half.
Since these two modifiers are cumulative, if your 20 hexes and 50 MP away from railhead, you will receive 0 supply.
TIP: It is usually easy to stay within 25 MP of the railhead even if you're more than 10 hexes away. Try not to be outside of both 25 MP and 10 hexes.
Unit Supply Draw Modifier (all units):
A unit will draw its supply Need (fatigue/experience modifiers notwithstanding - we don't have any math to model those) as follows:
A unit will draw it's Need, modified as follows:
100-(the distance in MPs to its supply source*-5)
*Note that for units within 5 hexes, the source will be the HQ most likely.
So if you have an armored unit with 50 MP, and you spend all 50 MP, supply received will equal 45 percent of Need.
TIP: Move efficiently. This is especially true for HQs themselves, as they supply their units.
I can't find it in the manual, but an HQ's distance to railhead, when under 10, will see an INCREASE in the amount of supplies delivered.
The single best ways that I have found to increase the natural flow of supplies to panzer units is this:
Get their HQ to within 10 of the railhead
Don't move the panzer unit for 1 turn.
Knowing all of these, and figuring out when and where to violate the 10-hex distance, will go a long way to improving your panzer MPs available.
