Is this correct? For the French Army to get full command structure 'dice roll' reorganization after unit disruption, Grand General "Gorgeous" Georges must be within command range of OG 1er Group Billotte, who must be within command range of the various army corps commanders, who then must be within command of their various corps commanders, who must be in command of their divisions? That's 5 levels of command to cover the entire front from Antwerpen to Sedan. Is that an 80% chance for re-order? Plus, the BEF commander Gort must also fall within Georges and Billotte's command range. Suppose an army commander is outside this range? That would be 3 levels of command, army, corps, division? Would that be a 50% chance for units to recover from disorder? Jonny Mac.
The only HQ you have to worry about when it comes to rallying the troops is the HQ of the unit. If the Battalion is within range of the HQ, you will get a chance to rally. If it is outside of this range, then there is a 50-50 chance that it will get a chance to rally. The other HQ's up the chain of command do not matter. What they do matter for, is whether your HQ will be in command itself. An HQ within range of its parent HQ will get two chances to avoid going OUT OF COMMAND. There may be some other small benefits, bonuses to resupply and such, but the simple rule of thumb to observe is keep your units in command range of their HQ.
When you play the Russians, it is practically impossible to keep all the HQ's in proper range. The French are probably similar.
Note that for supply checks, a unit is checked to see if it is in command from its HQ, by checking its distance with the HQ, between 100% at range 0 to 50% at max range (and scaled in between). If you are outside of your HQ's command, you will automatically fail and go low ammo/low fuel.
There are some other subtlties to the system to note....A corp HQ will probably have assets such as artillery, which can assist any of the divisions of that corp. An army/front could have the same. As well, you can usually hand those assets off to another corp under corp attachments.
Also keep your higher command HQ's near the most important part of the front. One can not command the entire front in a campaign game, but must decide where the extra help in keeping subordinate HQ's in command is needed the most.

Liquid Sky says it doesn't matter except to re-order. Why then do all HQs have a command radius? Why is there a chain of command? Is there a chain of command, and if so, why does it matter? Why does the French commanding General have a command radius if Sky is right? Jonny Mac
Read all of his comments - if lower level HQs are within the higher command radius, and the parent HQ is in command, then the lower level will get a second try at being in command if the first fails. So there is no direct impact on the lower level HQ's subordinate units/HQs, but there is an increased chance of the lower level HQ being in command which thus makes it more effective. And there are the subordinate units to the higher level HQ, which should be massed close to the higher level HQ, which strengthens that part of the line significantly, at least when there are directly attached units.
As ALL HQs can have subordinate units, they would have to have a command radius anyway, even if in a specific OOB maybe they won't. But there is still the benefit to the lower level HQs being in command.
