I very rarely defend my land and its becoming a problem now. Most of my military is almost always in my cities. Its like, the moment I move out of my cities, I wish I would have kept them in defending. On the other hand, I can't afford to lose my only source of iron, oil, horses or whatever. I am wondering what others do to defend key resource locations? I am tired of losing valuable improvements to AI attacks. The thing is, it takes a large military to try and defend your land areas in addition to the cities. Also, what about stacking some troops near the borders? Does anyone actually do this? In some games I tried it and was fairly effective but expnsive. It feels good to know you have a wall of troops defending your border so the AI can only get through a couple of areas if it were to attack. I think I need some tips on these things. It seems even at peace it makes alot of sense to at least defend key resource locations. Also, if diplomacy and relations is not so good with a neighboring country, maybe the border troops are good ideas.
