For a superb round up of Ogre Kingdom Army tactics check out Randroid's Ogre Army Book review on episode 28 of the Waaagh Cast podcast.
I have only just discovered this podcast, it's very impressive, there is a wide variety of top quality content (not only Orcs and Goblins !) and it's presented in a very friendly "buddy to buddy" way.
Randroid (from the Battle Reporter forum and Ogre Stronghold) told me about it because he was interviewed on Ogre Tactics and Army Selection (his interview begins about 26 mins after the start of Episode 28 - copy below link into your browser). It's quite a long interview and he really gets to show off his experience offering some interesting insights into Ogres and why he doesn't always opt for the more common army selections).

I plan to listen to these Waaagh Casts while I paint up my Nautican army.
I've also added the Waaagh Cast to the Battle Reporter forum allies blogroll.
