Very new to 40k rpg and I have a simple question about Talents for adversaries. On page 364 for the ork Boy Troop data there are 7 talents listed. Does every ork encountered have all of those talents?

Unless the GM says otherwise, yep

Its a template.

So if you need an Ork the quick way, you can take this.

You are free to modifiy this of course or make adjustments, as Orks might differ from each other.
