Hidden shooter (6)
I believe the answer is:
sniper
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">hidden shooter</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 sniper that I've seen before include "one who takes pot from a safe place" , "He shoots form cover" , "He shoots from hiding-place" , "One aiming" , "One shoots from a concealed place" .)
