What is Army expansion?
That sentence is the only income rule in the official description. It gives no rate, no cap, and no currency name beyond the cash players spend in play. Base upgrades matter because they are how recruits and vehicle unlocks arrive, which is the condition the sentence names. The description does not say a building has its own income multiplier.
