Hmmmm. And how does that affect academy graduate generation?
Not in the slightest.
Are you sure? I mean, if you add a rank, you have to rename every other one since the new one is added at the top, above Fleet Admiral/General of the Army. And if you remove, say, the bottom one (Major/Lt Cmdr), do the academies begin producing that now-bottom one (Lt Col/Cmdr) in the volumes the previous one appeared? How does the game evaluate how many Ground Combat Command points to give a new/reshuffled rank?
The numbers does not represent number of men but the total "size" of the formations under them. Also the game NEVER refer to number of actual soldiers but units. You could easily have an infantry unit be referring to a fire-team of three soldier or an infantry unit with a CAP is a machine gun team of 5-6 men. Like wise one infantry unit could be a super soldier like a space marine in power armour and a bolter. A light vehicle could be a small walker or a space marine Dreadnought type individual.
The number that each commander can command is their capacity, there is nothing that says that a colonel could not command a divisions... I mean he is capable of it... he just have not attained that rank yet. You probably also could find generals that are not capable of commanding a division even though they have the rank to do so... that is how real life actually works...
While there may be political influence, personal and other factors, ranks are generally a measure of experience in the service, and not just a title. You wouldn't promote a private to command 10,000 men right out of boot camp, if you have any sense.
While Aurora may not consider individual soldiers per se, it does so implicitly in the size/power of units. There's bound to be one value which would roughly represent the influence of a single, average soldier. Perhaps that value is 5, the size of an infantry unit with light armour and personal weapons*. Or perhaps it corresponds to a fire team (4-5 men), since 5 tons of equipment might be too much for a single soldier.
Another possible point of reference is the tank (medium vehicle, medium armour, medium anti-vehicle), which adds up to 62 tons, which might be just enough for the machine itself (taking into account advancements in materials and lower weight than a modern MBT) and a measure of associated supplies and spare parts. Perhaps that's a mech instead, an Adeptus Astartes, or a T-Rex with lasers, but it remains the equivalent of a mainstay tank-like unit of the ground forces by modern standards.
Overall, I'm trying to figure out points of reference to come up with plausibly-sized military units of standard human troops (no mechs, no titanic Space Marines) without running into things like the defeat of what I had designed as an infantry brigade at the hands of what an NPR may call a company of standard human-sized grunts.
*This estimation roughly coincides with the following fragment from the
Professional Journal of the United States Army, Volume 24, Issues 1-2 (1944):
Again, the lesser weight of 5 tons could be attributed to advances in material sciences since WW2.
