Basic Battle Tactics?

[Akela]

So I guess in general I've been fielding large squads, primarily to avoid routing but I was also trying to take efficient advantage of the spells that affect a whole squad, like Strength of Giants. I did notice however that a lot of them weren't getting into the mix very often.

I'm going to experiment with breaking them up into smaller squads and spread out my line a bit. I like the idea someone mentioned of telling all melee to "attack rear" increasing the likelyhood that the enemy's front line will be flanked.

Now, if I break these units up into smaller squads, is it better to have 1 commander with 5 squads, or 5 commanders with 1 squad each. (Let me guess, it depends right?)
