At GBNI our senior members consist or members with relevant Ghostbusters cosplay over the age of 18. Also known as “Trooping” members, senior members have the option of taking part in all events as well as contributing to the group in help and support where possible.

Cadet members of GBNI are members with relevant Ghostbusters cosplay between the ages of 11 to 17. Cosplay with Cadet members is not as strict as with Senior members, and all Cadet members are giving help and support on their cosplay from Senior members, preparing them to graduate to be a Senior member when they turn 18.

Junior Cadet members are our youngest members of GBNI, all under the age of 11.

Junior Cadet members are just young fans of Ghostbusters, no cosplay or rules are needed to be a GBNI Junior Cadet, you just need to love Ghostbusters like the rest of us.

While cosplay is not required, we love to see our Junior cadets at selected events showing off how cool they look in whatever they have to wear.
