HQ zone of command size?

[VonWulfen]

Hello all.
I have just purchased the game.
I started the game and have been following XTRG's excellent tutorial videos while familiarizing myself with the menu system.
I may have missed something or maybe it appears in a later video.
When selecting an HQ unit I don't see any zone of command radius highlighted.
How many hexes does it cover?

[AlvaroSousa]

5 hex radius. Land units it affects have a small flag popup on them.

Many thanks, sir.
Nice and clear now I know what to look for.
What happens if say an inf division moves out of position but comes under the control of another HQ unit?
Does it automatically gain the HQ bonus or are units tied to certain HQ?

Manual p. 37 (do a search of the manual ctrl+f using headquarters)

Headquarters – HQs increase supply in their area and improve
surrounding units’ combat effectiveness depending on the general
assigned to the HQ. HQs defend but can’t attack. A supply truck used
on a headquarter will supply all units within a 1 hex radius of the
headquarters using the appropriate amount of supply trucks for each
unit. The HQ must be in a supplied hex to use this ability. HQs also
increase the map supply level of friendly hexes within a 5-hex radius
by +1 to a maximum of 8. Hexes not in supply will have a map supply
level of 1.

As far as I can tell HQ do not have direct relationships with units.
If a unit is in range of a HQ it gets the benefit - no conditions.

Many thanks, sir.

Is this radius and/or the benefit reduced based on local weather ?

from my experience the flags don't go away so no and it crosses water hexes too.

You need leadership for D-Day so yeah across is water
