Fusillade (5)
I believe the answer is:
salvo
'fusillade' is the definition.
(I know that fusillade can be written as salvo)
This is all the clue.
(Other definitions for salvo that I've seen before include "Ovals (anag)" , "Burst (of applause, insults, artillery etc)" , "Burst of artillery shots" , "Firing of guns as a salute" , "Rapid simultaneous shooting" .)
