Soldiers- This has been the most intensive and by far the longest to research, as there are many factors that contribute to this number. Firstly it has no bearing on the total units you have in fact you could have zero units but show 100000+ soldiers in the demo screen, you will see how in a second.
Factor 1- Population points. For every two population points from all your cities you get 1000 soldiers. So;
1pop = 0 soldiers
2pop= 1000
3pop= 1000
4pop= 2000
5pop= 2000
6pop= 3000 and so on.
Factor 2- Technologies. Discovering some technologies (mostly military but not exclusively) gives you extra soldiers. I have to say some of them struck me as a little strange, like Military tradition gives you zero but hunting gives you 2000, but I’m not here to argue about that. Here is the list of techs that give you soldiers. If they are not listed then they give zero soldiers.
(For BTS 3.17)
2000 soldiers – Sailing, Hunting, Mining, Animal Husbandry
4000 soldiers- Wheel, Alphabet, Astronomy, Metal Casting, Compass, Construction, Steel, Radio, Satellites
5000 soldiers- Composites, Stealth
6000 soldiers- Mathematics, Chemistry, Combustion, Archery
8000 soldiers- Guilds, Fission, Flight, Bronze Working, Machinery, Assembly Line
10000 soldiers- Horseback Riding, Iron Working, Artillery, Industrialism, Rocketry, Advanced Flight, Laser
12000 soldiers- Gunpowder, Rifling, Military Science
Factor 3- City Improvement/Wonders. Like discovering some technologies, build certain improvements and wonders will increase the amount of soldiers you have on the demo screen. In this case you amount added for each improvement. For example you get 2000 soldiers for each wall you build, so if you have 5 walls, you have an extra 10000 soldiers. With wonders that give you soldiers, you can only build one so you only get that bonus once. Here is the list of what you get for each improvement. Improvements that don’t give soldiers are not listed.
(For BTS 3.17)
1000 soldiers- Trading Post, Shale Plant, Totem Pole
2000 soldiers- Walls, Dry Dock, Castles, Forge, Factory, Stable, Mint, Assembly Plant, Industrial Park, Levee, Dike
3000 soldiers- Dun, Barracks, Ikhanda, Citadel
4000 soldiers- Mt. Rushmore, Red Cross, Iron works, Ger, Statue of Zeus
6000 soldiers- Military Acadamy
8000 soldiers- Heroic Epic, Chichen Itza, Scotland Yard, West Point
10000 soldiers- Great Wall, Cristor Redentor, Moai Statues
Factor 4- Units. Finally each unit type has a different amount of soldiers attached to it, so a warrior contributes 1000 soldiers, while a Swordsman is 3000 soldiers. Interestingly enough a units experience points has no bearing on the amount of soldiers it equates to. Units such as scouts, workers missionaries and spies contribute zero soldiers to the demo screen. Here is the full list of what you get for each unit;
