<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">armed bodies</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for forces that I've seen before include "Troops and weaponry" , "Troops; makes" , "Prizes" , "Compels or inflicts" , "Compel's the military" .)
