First, the big number. You get a whopping 15 detachments in the upcoming Codex: Orks, and thanks to the new detachment system that lets you mix-and-match your favourites, that means the number of possible combinations is higher than most Orks have ever learned to count.
Out of those 15, one is a big, two-page, classically sized detachment, similar to what you’re used to from the last edition. This is the one to take if you want a bit of everything and some rules that’ll work whether you’re speeding around in Deffkoptas or getting stuck into close combat with your Nobz. The rest are smaller, specialised, one-page detachments that focus on a few key units, so you can build exactly what you want and always get the most out of your favourite miniatures.
Take these two, for example. Runt Swarm is the new home of Battleline Gretchin, so if you’re not up for a Dread Mob kind of game, you don’t have to tie your swarms of little blighters to their stompy cousins any more. The Sneaky Little Gitz rule also solidifies their role as a cheap and expendable unit that can sprint up the field, complete a mission action, then die horribly with their job fulfilled.
