Welcome to Librarium Online!
I can't seem to find the stats for the Orc Rokkit Launcha anywhere in the Orc codex. I don't suppose someone could post where in the codex I can find the stats?
Should be in the armoury section. That's where the stats for the weapons should be.
Or you can go to the GW site, and download the Ork summary.
Got it from thier website. Thanks for the help, I didn't realize that they had summary's on there.
