Not a guru answer, but in response to "can shed some light on how the AI manages major battles with respect to their historical accuracy", even the undocumented and uncontested king of RGG timing, lurker_hlb3, could not bend the game 100% to his will. It would ~still~ whack-out on him for unknown and unforseen reasons known only to the AI. Even the game engine was unaware of what the AI was up to... Besides the fact that the game will not spawn planes in response to planes, nor do dogfights... but alas, I digress. The game doesn't do too bad as a subsim (while you're underwater with your scope down - so long as you stay in your seat), but get much more than that, and its age and technology really show their skivvies and hinder parts...
