VIP Bodyguard
VIPs are sometimes difficult people to get along with. They want this and that, and want it as soon as they ask for it. So a VIP Bodyguard has not only to guarantee for the safety of the person s/he guards, but must also be good at organizing the requests from VIPs. VIP Bodyguards work with Mainstream Security generally but are ready to step in and work as a VIP Bodyguard when neccesary. VIP Bdyguards go through extensive training with the Close Protection Division of Starfleet to become qualified to work there.
More than once s/he has to be diplomatic about what s/he has heard while staying in the vicinity of there VIP guests.
As with Brig Officers, VIP Bodyguards are specialist Security Officers, and when not serving a VIP most Bodyguards partake in normal Security duties.
