All orks have an innate understanding of technology, some orks just go with it, and a few are oddboyz who focus on it. Normally known as mekboyz.
He'd probably have some grasp of what it does if he sees one. And it's a gun that shoots hot stuff, most orks and even some mekboyz don't even care after that part. Just point and pull the trigger.
Or a melta bomb. Orks are generally chaotic enough to just get them to work. Although that's with the gestalt field. Meh, Urgrugg is a nob, he's probably seen 'umies use melta bombs before.
And JB.
Imma gonna open a door on the scout ship. People will have to get their asses out of the lander and to the door themselves.
I mean come on, they are space marines and a warphead. Surely they can get that far no problem without a twitchy psychotic heretek holding their hands?
I'm working on getting people aboard the ship so we can have some interesting stuff go on again. So i'm just waiting for:
Someone to contact Zuriel.
People starting to mill about outside the lander.
Muck about long enough so Zuriel goes tired of their lazy asses and contact them to get their asses moving.
Also, i could meet up with the renegade guardsmen. I'm sure we'd have a wonderful time :)
