Use of HQ units

[ComradeP]

Units operating outside the command range of their HQ's ("detached") can't recover from Low Ammo and Low Fuel status as those require a range check to the HQ. They can still pass the ammo test if they're detached if they pass the first test based on the local supply level. They just can't recover from Low Ammo status whilst being detached.

Detached units spot for indirect fire at half value.

Detached units receive 1/4 replacements through the replacement mechanic, but as far as I can tell the manual doesn't mention the effect of being detached on the recovery mechanic.

I try to keep all units comfortably within HQ range, as there are benefits to HQ's being close to their units, but in most cases infantry formations temporarily being out of command range won't be lead to disaster if they're B quality or above. Mobile units, or anything using fuel, is ideally always within the command range of its HQ.

The user manual specifies the effect of HQ's on various mechanics in the paragraphs on those mechanics.
