<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">gun volley</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 "Outburst, as of applause" , "Rapid simultaneous shooting" , "concentrated fire" , "Firing of guns as a salute" , "A volley of shots, perhaps as salute" .)
