These are pretty cool - not sure what i would use them
how about an inquisitor acolyte or something, I don't know about arming them, but the joke rights it self. (PS: it works best if the Sectary sounds board in your head)
Inquisitor machine gun : DAKKA DAKKA DAK-(keeps shooting)
Inquisitor: Kimberly: did you get the reports from the governor about his investigation?
Sectary: Right here sir he claims the local Arbitus: Ganger with bolter 8 o clock sir: found little evidence of chaos involvement in the local upriseings.
Inquisitor: No chaos involvement! by the throne are they: (stops shooting) hand me another belt!.
Secretary: here sir.
Inquisitor: good (resumes firing): are they blind! We will see the truth of the matter! Kimberly! ready the inductor fourm! I'll need to draft the PDF regiment!
Secretary: Very good sir: they will be ready in three. five minutes.
