Enhanced DBS (Disclosure and "baring" service).
Who carries out this DBS? Who appoints them.?
If adults are volunteering for these Instructor roles Why are they?
Young boys and girls?
A free uniform worn with no guns firing?
These comments are somewhat concerning, why would that be your first concern. Comments such as these would raise alarm bells about your intentions, not those wanting to be instructors. Have you ever thought that there are some people out there that do want to help!
