A private security guard is a civilian.

BTW, is anyone else wondering why a church has an armed security
guard???

That is a mega-church something like 15K parishoners, IIRC. Would seem
that the collection plate alone would warrant armed security guards.
Also, don't know if they got them mostly for traffic control and the
guns just happened to come along with the persons assigned (although
from my misspent youth as a Pinkerton guard, those qualified to carry
firearms usually got paid more and cost more.)
