So within a dozen or so turns I will have the planetary invasion tech and can start building ground troops, but I have a few questions:
1. Since ground troops cost pops, how many troops should be recruited from each world before it starts to harm the economy too much?
2. If pops are recruited into troops and send into space in a transport ship, will the planet regrow the lost pop even though the original pop hasn't been killed yet?
3. If 2 is true, then how wise is it to maintain a standing ground army during peace time? And how large should such an army be?
