Imperial Wolfbane tactic:
I mentioned this in the favorite character thread but one of my favorite tactics with my Wolfpack army: Two large squads of Wolfbane commandos each with a Wolfbane Vanquisher in command and at least 2 HMG's. Add to this either Sean Gallagher or a Wolfbane Packmaster or an Elder Chieftain as an individual. These three units start the game in close proximity. I activate one squad of wolfbanes and move them, except for the HMG's, I use their form Fireteam to break off and become a seperate unit. THe last one to move is the Vanquisher and his last action is to activate the second squad of wolfbane commandos. They do the same thing, the HMG's break off and form fireteam with the other two HMGs. I now have a squad of at least 4 and up to 6 HMG's. The squads provide cover for the HMG's until they can get into a good cover position to fire upon the enemy. The individual stays close to the HMG's and can activate them when needed and provide morale support. When you get them to range, the HMG's can devastate whole squads giving them the firepower of an artillery unit. You can also keep the HMG's two seperate fire teams in order to cover different fire lanes or the same one from two different points to cover any 'blind' spots.
Dark Legion - Muawijhe: The Gibbering Horde - A Doomsday Proclaimer with several squads of Karnophages, 1 or 2 squads of Zenethian Soulslayers, a Slaughtermaster and some fire support using two squads of Screaming Legionaires. This is a fast attack CC army. The Karnophages and Doomsday Proclaimer both have a movement of 5". The Zenethians have a movement rate of 4". I devastated a Bauhaus army with this army. I had the Karnophages and Doomsday on one flank, shooty guys in the middle, Zenthians on the other flank. This was on a trench board, with the Bauhaus entrenched with Vulcans on one flank that were outside the trenches. There were 12" of open area to cross. I sent the Zenethians after the vulcans, the Doomsday group went after the guys in the trenches. The shambling horde advanced up the middle with move move shoot and their Golem of Darkness slightly in the lead to draw bullets and use his Aura of Darkness once he made it to within 6". By Turn 4 most of the Bauhaus in the trenches were either dead or routed with stained pants. The Vulcans were taken out with the loss of only 1 Soulslayer.
