I have had a look around but couldn't find anything.

So I was wondering where I could hire Nautolan Riflemen specifically. Like what planet and any other information that might be important.

Thanks guys.

from the Hiring section of http://www.swcombine.com/rules/?NPCs:

The race of each NPC is based on the planet where hiring and on the restrictions linked to the race. When hiring on a homeworld, there is 90% chance to get a NPC from the native race. In all other cases, the race will be randomly selected.

Alright cheers Syn, must have skipped over that bit.

EDIT: Thanks Syn :)
