Perhaps this was a misconception from the stories I was reading, but I thought they would impale themselves on my infantry army if it was in a city - something about the city makes them suicidal. The enemy cavalry certainly did this. But the infantry and guerillas would just hang around and pillage tiles. So I wonder if I would have been better off just stocking the city with infantry. Sure, I would lose some to the RNG, but it would make the mop up easier. The majority would die via impalement, my defensive units would promote to elite and maybe pick up some GL while my armies terrorize the countryside. On the other hand, I was bombarding them with my artillery and few units were left at full health even at the beginning. It wasn't long before every unit that step next to the city was redlined immediately. Another thing I learned previous to this was the AI will go after radar towers much like towns. In the past I've put a cav army on top of a radar tower thinking the AI would avoid attacking. Nope. An interesting observation is that the AI would bomb armies in the open field via artillery (if I was close enough to a city with an artillery piece) or with bombers. But they never even attempted to bomb an army in a city with their bombers. I know the AI is horrible with bombarding units, which is a natural advantage for the human player. But they didn't even bother to try a bombing run. I know from past experience that bombers pick 'high value' targets like luxuries and resources, even if I have dozen more like it back home. You would think the AI would prioritize a landing city instead and send at least one bomber in that direction. Lastly - you mention the chance of a flip. I did worry about this, which is why I asked how fast the average player moves out from the initial landing. If one of those initial cities had flipped, it would have seriously hampered or even destroyed the landing.
