Losing an army HQ-Oh no!

[ComradeP]

It should reappear normally at some point in a hex with one of the units it commands.

What I don't know is if it reappears in a hex with a unit that is directly subordinate to it (army HQ's, whatever units are directly attached to the Serbian Army HQ in the scenario you're playing) or in a hex with a unit belonging to its organization. If that's the case, it might reappear in any hex with a Serbian unit.

The main effect will be somewhat worse results for checks where a higher HQ down the line can help, such as Command checks, and any checks done by the HQ for units directly subordinate to it, such as Disruption recovery, Replacements and Ammo/Fuel checks.
