Does tech disparity affect promotion chances?

[RedBird]

I've read a bunch of threads regarding promotion, and I haven't seen this mentioned anywhere, but I was curious if someone could provide a definitive answer. Does the technological disparity between attacker and defender affect the probability that the victor will get promoted?

e.g.: if I attack barbarians with my swordsman, and then later in the game attack barbarians with Mech Infantry, will the swordsman have a better chance of getting promoted (presumably because the fight would be too easy to warrant a promotion for MI)? [I know that attacking barb's does not gen GL's, and I know that each successive promo level is more difficult to obtain].

From what I have seen, no - and with the civ3 combat model it does leave room for freakish battle outcomes.

A battle is a battle , and if you win promotion is warranted

I believe the promotion chance is halved when fighting barbarians. Also, it seems any unit winning 2 battles in one turn is automatically promoted, barbarians or not.

I concurr w/ the 2 battles/turn theory. At least my experience confirms that.

Unfortunately, my experience is usually something like:
"our Regular x is now Veteran", "Our Veteran x is now Elite," and then I usually have to add, "Our Elite x is now Dead."
