When I look at high level cities, they often have tons of units, especially light infantry, showing on their city screen. My light infantry are all contained in my light infantry building square (lvl 20). When more units are shown in a city, is this based on the military building level being higher than 20, or on the player actually having huge numbers of that type of unit? TIA.

Are you referring to these and similar units?

That is decor which contributes to the CDB (city defence bonus) but is completely unrelated to any "real" units the player might or might not have.
