Lootas are Ork specialists obsessed with two things:
- Making the biggest bangs
- Nickin' stuff.
These obsessions define their twin roles in Ork society. In war they are the heavy weapons specialists, wielding the horrifying (for their targets, for anybody near their targets, and for anybody anywhere near the lootas) Deffgunz, the ultimate Ork-portable testament to the philosophy of MOAR DAKKA. Deffgunz are cobbled together by lootas and Meks with the goal of creating more noise and delivering more firepower in a vaguely downrange direction. Often this just means they weld or ducttape 'recovered' weapons from the battlefield on to a frame and slave the triggers together.
Off the battlefield, however, they're more like heavily-armed scavengers. Lootas, good to their name, excel at looting. They infiltrate enemy camps to steal weapons and vehicles which they rebuild to fit ork sensibilities and tactics. Lootas and Mekboyz have a close relationship; the lootas often bring meks the best gubbinz to work with, as long as the meks give them better deffgunz and vehicles to use. However, Loota's attitudes regarding property extend to more than just other races, and they have no problem stealing from other orks. Many boyz consider lootas a bunch of thieving jerks that need to keep their grubby klaws to themselves.
Lootas are a very popular choice for Ork players. They have just about the longest ranged dakka in the Ork codex and wound almost everything on 2's with their S7. Their guns are Heavy d3; each shooting attack they make they roll a d3, and that's how many shots each Loota gets. On the downside, they suck in melee, relying on Overwatch to protect them. You also have the option of replacing up to three Lootas with Mekboyz, in case you feel you need more Rokkit Launchas.
