They may be responsible for reports from the front (7)
I believe the answer is:
gunners
'they' is the definition.
Both the answer and definition are plural nouns.
Maybe you can see an association between them that I can't see?
'responsible for reports from the front' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'un' (I've seen this in other clues) and 'un' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'may be' is the link.
Can you help me to learn more?
(Other definitions for gunners that I've seen before include "Artillerymen" , "Artillery soldiers" , "The RA" .)
