Ok, that I understand.
I suspect a lot of AFBs are not allowing upgrades to restricted units until they buy them out, and by then you are further down the AFV upgrade path skipping plentiful machines for the top of the line precious ones.
Years back M-M I think came up with a tactic of stripping the tractors from IJA heavy artillery since they are useless mouths. I argued at the time, and he eventually discovered, that those useless mouths acts as a damage sponge...soaking up damage that would otherwise go to the AFV in your example. With IJA heavy artillery, stripping off the tractors made the unit very fragile and subject to destruction very easily.
Hazy memory on that, it was quite a while back. I'm sure it was in those late war bombardment duels or Chungkingrad that this cropped up. Essentially a bit of a catch-22, as IIRC the tractors are quite squishy and cost VEH points, but as the units are normally small (ie, 4 guns or so) they can be easily wiped out if the tractors aren't there to give them a cushion.
I wrote far to much on pool management, so I'll condense it down as far as possible.
- watch the tanks closely, and check tracker for the "correct" upgrade path.
- in Japanese terms, all tanks are created equal as the IJA lacks the anti-armour firepower to really get a handle on nearly every "proper" Allied tank. Matilda's are suitable for frontline combat almost the entire war, so don't be afraid to leave big tank units using them. They're surprising similar in stats to a M26 Perishing...
- the shared Commonwealth device pool is a blessing and a curse, need to watch that it goes where needed. Don't want NZ soaking up the PIATs and the 25 pounder guns.
- I remember a big challenge was timely upgrades of infantry squads, especially around the Australian Army. There's a notable difference in the '42 upgrades for the Commonwealth forces, and a massive difference in '43, so getting them out as fast as possible is a massive priority.
