I believe the answer is:
awol
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">army no-show</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 awol that I've seen before include "Truant (or just missing)" , "Not present when supposed to be" , "unaccounted for" , "Missing without permission" , "'Absent without permission, initially (4)'" .)
