Army manoeuvres get her agitated (4)
I believe the answer is:
mary
'her agitated' is the definition.
I can't tell whether this defines the answer.
'army manoeuvres' is the wordplay.
'manoeuvres' indicates anagramming the letters (letters manoeuvred in a new way).
'army' with letters rearranged gives 'MARY'.
'get' is the link.
Can you help me to learn more?
(Other definitions for mary that I've seen before include "Person venerated by Christians" , "Sinner who became a follower of Jesus" , "feature of 21/23 [NATIVITY SCENE]" , "could be Wesley" , "a religious icon" .)
