Damaged first of Harriers carrying weapons (6)
I believe the answer is:
harmed
'damaged' is the definition.
(thesaurus)
'first of harriers carrying weapons' is the wordplay.
'first of' indicates taking the first letters.
'carrying weapons' becomes 'armed' (I've seen this before).
The initial letter of 'harriers' is 'h'.
'h'+'armed'='HARMED'
(Other definitions for harmed that I've seen before include "Hurt" , "Injured or damaged" .)
