Has anyone else noticed the withdrawal-blitz ability the AI has for all of it's fast attack units? The most notable usage is with attack subs who I've seen attack 4 or 5 times before dying. I used to think that I was being attacked by like 10 subs; eventually I realized that it was just a handful of subs attacking, withdrawing and attacking again. I've also noticed this with mounted units. I've seen cavalry attack, withdraw, and attack right away again. Then again, I don't really remember attempting to see if my units can do the same. At any rate, even if my units also possess this ability, this should be considered a game error because this is a function that is only supposed to exist for blitz promoted units. Editing Note: After lengthy discussion, it has now been proven that in a specific scenario, AI attack subs can attack and withdraw for as many times as it has movement points available. This scenario is when a human player assigns naval ships to protect resources by utilizing the patrol function. Any AI ship that attempts to pillage those resources may do so for as many times as it has movement points available, thus via a mechanism of the game, each attempt at pillaging will result in combat between the attacking sub and the defender. It has also been shown that mounted units do not possess this ability, since no patrol feature exists for land units. Although, it would be interesting if a patrol feature did exist for land units, whereby you could assign sally defenders for cottages and resources. That's a feature we need.
