Not meaning to step on any toes but can somebody suggest what I'm doing wrong (other than losing too many troops)

Well, in a way I think you've already answered your own question there - but I would say play more; building your own experience is the key. I think you'll find that the AI is not quite such an impossible opponent, though it is much more advanced than what I suspect you are used to from other SP games.

It would be interesting to know the settings you use for your campaign - map size, core etc...
