Well it should be pretty obvious what my favorite Heavy Support choice is from the mighty tome of Chaos. Obliterators are diverse, powerful, hideable, teleportable, and worth every point. But they are not the only HVY SPRT choice. I was talking to a friend who is considering getting into the hobby and he asked me why take Obliterators compared to the Havocs. And I replied in my best comic book guy impersination, Obliterators are the best Hvy Sprt choice ever! I still stand by that but lets look at some of the other heavies. Havocs!! - to devastate, to create ruinous damage. Ahh how appropriate!
I hate to say it but I think the best place for this heavy is in a fluff army. Death Guard immediately comes to mind since you can take special weapons as well as Heavy Weapons. In fact, this is about the only combo or build that I think would be worth it in a competitive game. 4 meltas in a minimum squad of Kamakazi chaos marines with a rhino to get them to the Land Raider full of Hammer Termies. However, I do this with 5 meltas in a outflanking squad of chosen for just another 3 pts per model.
The squad can start to get expensive if you take 4 lascannons and 10 chaos marines at 290 pts. Especially marines who arent fearless or cant regroup if they fall back below half strength. And thats without a rhino. A rhino? Yeah, if you can take a rhino for 35pts, you should. Use it somewhere else! As a empty decoy along side full rhinos, or as mobile cover. And dont you EVER take a champion in a havoc squad. EVER! If you do and I find out about it, I will tell Abaddon on you!
4 lascannons is taking the expensive extreme but if you want to mix in other weapons you start to loss some punching power. A mix of anti tank and anti infantry would reduce the effectivness your unit has. It is best to try and decide what the unit will be used for before the game. In a well balanced army, a Chaos Lord will have the ability to deal with both armour and mobs of infantry, but not necessarily with the same unit. Im not calling anyone out if you mix your havocs, Im just saying that I think they can only really fill one roll.
Death to the False Emperor!!!!!!!!!!!!
