Mr Black: Actually, those 'other guys' would be REMFs 
Basically a unit is whatever size fits your playing style. For me that's usually brigade-sized units - wings for most aircraft types, single units for larger ships and squadrons for the smaller units, with older military units being "a couple of thousand guys".
I say it depends on your style, because anyone building a small military might think of the units as larger, anyone with 100s of MA probably will think of each as a battalion or smaller.
If you can be bothered you can try to deduce unit sizes based on population sizes of cities and the number of military a city can support (or the number of draftees you can have). I did it once, but it's a bit of a fool's errand.
VC: If a carrier unit is a group of carriers, how come they can only base a total of 4 air units, which you say would be 4 aircraft??? More realistic is that each carrier unit is a single CV (escorts if you like, though not many, since a carrier is a weak surface unit) and each air unit about 10-20 - which would give something like 60 total aircraft per carrier, which is close enough.
