you're free to work out your military any way you wish, but if you're planning to roleplay with that information, it needs to make sense. For example, if you had a terrible economy (and you don't), you'd have to have a realistically small military, because that's all you could afford.
We typically use militaries of 1% of our current population. For example, 5% would give you an economy something like North Korea's.
ah. thanks much. sorry for going to the wrong place. i figured since it was a rp place people would kno what they were talking about. forgive my mistake.
