Some of the civic arrangements for the serviceman (5)
I believe the answer is:
vicar
'the serviceman' is the definition.
(I've seen this before)
'some of the civic arrangements for' is the wordplay.
'some of' says the answer is hidden in the clue.
'VICAR' can be found hidden inside 'civic arrangements for'.
(Other definitions for vicar that I've seen before include "See stand-in" , "Cleric" , "clerical worker" , "one brought in for service?" , "Parson" .)
