I am mostly asking for army size reasons. Considering my nation is not at war, their army size would be fairly limited. I use a percent rule for calculating typical sizes, with 2% of the total population for peacetime, 5% for wartime, and 10% if the war goes belly-up.

With these numbers in mind, my lowest population (220,000) would mean the army size would be as follows:
4,400 for peacetime
11,000 for wartime
22,000 as a last resort
I personally like these numbers, as they are nothing that can be used to launch a world war, but are big enough to defend their territory. Again, though. I have no idea what other army sizes look like for other nations.
