Questions from my first scenario...

Sadly, the strength dialog is less useful than it could be, as it doesn't show HQ units in most cases, nor their location, so the main way of pinpointing where a HQ is would be to open the campaign map and see where it is relative to the location of the HQ in the current scenario.

It's cumbersome, and as Dog Soldier wrote some HQ's might not be physically present in the campaign scenario either.
