I'm having a hard time assembling your various thoughts into a coherent understanding of what I need to do, 'cause I'm kinda slow, ya know?
If I'm reading you guys correctly, you're telling me for upgrade purposes it is sufficient to have a command HQ (Southeastern Asia, for instances) within 9 hexes of Akyab (or is it 18, per Loka's comment?). Then, if Akyab has supply, units can upgrade devices/TOE.
Do the units have to be in Akyab to upgrade or can they be within some certain radius of the hex?
Or have I just screwed this all up, failing to understand what you've patiently explained?
Two different things:
TOE upgrade: Command HQ within 18 hexes, unit set to rest, at a friendly base. The TOE will upgrade.
Replacing old devices with new model devices: Trickier to do, and I am not aware that Command HQ does in fact help, but it can't hurt.
First and foremost you need access to base with a minimum of 2x the required supply. In fact you might need in excess of 20,000 supply but I don't think so. I can't remember when one of my units upgraded in the field and not at a base. Often times you will see a operation report line...
Device(s) upgraded in 5th Division supplied from Prome
On this particular day there was a command HQ within range, Prome had more than 2x supply than required, and over 20,000 supply, and the 5th Division was in Prome. That unit one hex away from Prome didn't upgrad their devices, but the first day in Prome they did.
I have no idea what impact the command HQ may or may not have had.
As I understand it the new device cost supply to make for Japan; I need to have enough supply at the base to meet that supply without going below the 2x required supply for the base (I think). The supply is converted from the base into the devices and placed into the unit, old devices go back to the pool. I also need the raw material inputs to make the device if they didn't already exist in my pool. They are in Allied pools so you need not worry about that.
Is there an administrative leadership impact. No clue.
EDIT: I went back and checked in Tracker...I have upgraded devices at bases with less than 20,000 supply. But I still do think you need in excess of 2x base supply the cost of the device upgrade in supply for the upgrade to take place.
