Fellows of Armenia (3)
I believe the answer is:
men
'fellows' is the definition.
(fellow can mean a man)
'of armenia' is the wordplay.
'of' indicates the answer is hidden within the clue.
'MEN' is hidden in the letters of 'armenia'.
(Other definitions for men that I've seen before include "'So many ..., so many opinions'" , "Males of Armenian extraction." , "Adult males" , "Soldiers" , "Human males" .)
