I don't know how it works, never used, I will documented me.
But if it is better why not ! 👍

I took a quick look at it.
Why you didn't create a section per city instead of a big array?

It was a very superficial look, so it could be a dump question.

Excellent question:
city isn't activate or without enemy have a very short array. So to avoid iniDB call, I prefer to use your structure : array of city.
In array of city there are data_units : For city activated there are a lot of data_units , I am storing it in a separate array from the array of city https://github.com/Vdauphin/HeartsAndMinds/pull/83/files#diff-565056a6ba66b390c17e1f0d44a9b70cR44.
And for city activate with no data_units, I am not calling iniDB https://github.com/Vdauphin/HeartsAndMinds/pull/83/files#diff-a225bbf1a18afcd53b2e321d46f2153bR11.

This solution is very effective because I found very quick the sub array with the correct length https://github.com/Vdauphin/HeartsAndMinds/pull/83/files#diff-a225bbf1a18afcd53b2e321d46f2153bR32 and there are a vey low iniDB call.
