Army personnel will feed them (9)
I believe the answer is:
anteaters
'army personnel will' is the definition.
I can't tell whether this definition defines the answer.
'feed them' is the wordplay.
I cannot quite see how this works, but
'feed' could be 'eat' (I've seen this before) and 'eat' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for anteaters that I've seen before include "More than one insectivore" , "they take in the workers" .)
