Fluko(s) and Fluwa(s)

Fluko = Flugwachkommando = observer post detachment
Fluwa = Flugwache = observer post

IIRC, each Fluko subordinated a number of Flugwache. The Fluko was usually in a city, town or command and control bunker, while a Flugwache consisted of one or two people with binoculars posted on a rooftop or nearby hill to keep on the lookout for approaching aircraft. The Flugwache generally reported by telephone while the Fluko were equipped with both telephone and radio capability.

Horst and SES might be able to fine tune these definitions with some additional information.
