Denounce loudly male unit being disbanded (9)
I believe the answer is:
fulminate
'denounce' is the definition.
(fulminating is a kind of denouncing)
'loudly male unit being disbanded' is the wordplay.
'loudly' becomes 'f' (short for forte - 'loud' in music).
'being disbanded' indicates anagramming the letters (I've seen this in other clues).
'male'+'unit'='maleunit'
'maleunit' is an anagram of 'ulminate'.
'f'+'ulminate'='FULMINATE'
(Other definitions for fulminate that I've seen before include "Explode with anger, criticism" , "Protest loudly and bitterly" , "blow out" , "Rail" .)
