I believe the answer is:
salvo
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">gun salute</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for salvo that I've seen before include "Artillery salute" , "concentrated fire" , "A number of shots" , "Series of shots" , "Simultaneous artillery fire" .)
