He parades around front line (9)
I believe the answer is:
spearhead
'front line' is the definition.
(thesaurus)
'he parades around' is the wordplay.
'around' indicates anagramming the letters.
'he'+'parades'='heparades'
'heparades' with letters rearranged gives 'SPEARHEAD'.
(Other definitions for spearhead that I've seen before include "front" , "come first" , "Advanced troops" , "initiate attack" , "Part of weapon possibly iron" .)
