I believe the answer is:
serviceman
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">member of the armed forces</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for serviceman that I've seen before include "Private" , "Member of the armed forces" , "Tommy" , "car maintained by him?" .)
