Coming in HOT after a small points reduction to some key units it's Destruction's finest multi-wound, semi elite force. This faction is packed with solid, durable units and very few of them deal less than 2 damage with each swing of their weapon and some brutal syngergies.

Where to start?

Well obviously we need to get a hero and at least two battleline choices. Starting with the Hero choice, the Gutbusters have two of these. The Tyrant is a melee bruiser who can smack most other heroes into line, with a randomly generated bonus trait not unlike a command trait and a toasty command ability that lets him inflict D3 mortal wounds on a friendly Gutbuster unit to make it totally immune to battleshock. The Butcher is the wizard choice, usually taken with the optional Great Cauldron option that gives him a random ability that can heal or harm. Obviously with only two hero choices, we'll probably end up having some of each of these two. As battleline goes, you've got Ogors (generic battleline), and Leadbelchers and Ironguts (Gutbusters battleline). The Ogors are your rank and file, packing 4 wounds and decent damage. The Leadbelchers are more of the same but packing decent firearms as well. The Ironguts are your elite infantry, horrifyingly brutal in close combat and capable of taking down basically anything.

Where to next?

Now we have the foundation, we need to tack on some utility. Often overlooked in this allegiance are the Grots, these cheap little gobbos can net objectives and form decent screens to prevent your valuable troops being closed on by enemy assets. Furthermore, the Tyrant can make them permanently immune to battleshock, which is exceptionally useful. For shooting, Leadbelchers are already passable but to mix some artillery in we have the Grot Scraplauncher (good at dicing hordes) and the Ironblaster (high rend that does ok against numbers but is better served shooting at high wound single models. Also weirdly good at close combat). There's also Gorgers, a flanking option that's also relatively cheap. They are made from finecast however, so consider converting some out of Flesh Eater Crypt Haunters.

Adding in Allies

Keeping with the Ogor theme, both the Stonehorn and Thundertusk Beastriders can be allied in at 2k points, and the Frostlord on either mount can tag along at 2.5k. For less extravegant options consider the Maneaters, an elite Ogor unit which is both flexible and fun to convert up, and various trolls from the Troggoths units for some seriously durable units.

In this list I opted out of any allies and doubled down hard on the powerful options already available to the faction. I left 50 points out to get an extra command point for a turn one Tyrant hits the grots and makes them immune to battleshock, then burn another command point if I dont roll a 6 on the grot run to get them right out in front of the army spread out. The slow moving Ogors can move up behind this grot phalanx (which will inevtiably die once sneezed on) until the enemy is within firing range. Their durability will allow the Ogors to hold the objecctives easily against the enemy.

Any Gutbusters players reading, definitely comment if I've missed anything. You guys are the real heroes.
