Hello everyone. I'm a total newcomer to the system and right now I going through the manual and tutorials. I'm not sure how do you attach units to a particular HQ? For example Corps II is attached to army A and now I want to attach it to army B. How do I go about it? The first answer that comes to my mind, is that I just need to stack the corps with an appropriate HQ. But what if the corps is not stacked with the HQ? Can it be still attached to it?
Another question - if a unit or stack of units is not attached to any particular army but it's within a range o a army group HQ. Will it benefit from it or will it be considered out of command? In other words, can the army group HQ's command units directly or can they only command the subordinate army HQ's?
