Star involved with East German officer (8,2,4)
I believe the answer is:
sergeant at arms
'officer' is the definition.
(sergeant at arms is a kind of officer)
'star involved with east german' is the wordplay.
'involved with' indicates an anagram (involved can mean confusing or complex).
'east'+'german'='eastgerman'
'star' with its letters anagrammed with 'eastgerman' makes 'SERGEANT-AT-ARMS'.
(Other definitions for sergeant at arms that I've seen before include "Officer of a legislative body maintaining order (G, not J)" , "officer trying to keep order" .)
