Is your mod available on CFC, Jorsalfare? I'm interested to see the AI actually using land transports - I've never seen that before. I'm also curious to try it out in my editor and see if I can figure out what is making it behave strangely - I have not experimented with units with strategies not appropriate to their class before. If it isn't currently available, that's all right, and I can experiment with it myself. Just figured I'd ask since it's easier to start with things already working.
Hi Quintillus. My mod is not released anywhere, I'm afraid (it's one of those pesky mod-mods discouraged on CFC

). I have started work on a new mod built from scratch, but it won't be finished for years (if ever).
Some info on the settings I have used in my mod:
I have given my land transport defensive strategies in addition to air transport, but maybe a offensive strategy could entice AI to use them more actively? Or does AI assign only one of the strategies to a unit - never two? I tried to only have air transport as strategy, but then I didn't see AI building them. Also, making them too weak seems to discourage AI from building them.
As Civinator points out
here, land transports gives the human player an advantage even when AI is using them. I agree with him, but I think they add new fun strategies, more gameplay and variety to my mod, so I choose to use them. I try to make sure they are not too powerful, since that of course ruins the fun (wheeled, carry only foot units and unable to embark early transport vessels).
However:
Land transports can actually also give AI an advantage (although small) in certain situations. When a land transport loaded with units is in a city, the loaded units will not be visible for an attacker until combat is initiated. The human player can therefore get a nasty surprise when then city's strongest defender turns out to be (for example) an elite pikeman rather than the injured regular spearman visible in the city prior to the attack. If the pikeman is defeated, the injured spearman once again becomes visible in the city. I'm not sure what happens if the pikeman wins the battle unscaved (if he is reloaded into the land transport or becomes visible as a city defender). I have several times failed to capture a city because two or three loaded land transports were present there. Other than that, the AI is inferior to a human player when it comes to utilize land transports for mobile warfare - at least as far as I have experienced.
