In disarray, hunts made opposing camps (4,3,2)
I believe the answer is:
them and us
'opposing camps' is the definition.
(two opposing groups)
'in disarray hunts made' is the wordplay.
'in disarray' indicates anagramming the letters.
'hunts'+'made'='huntsmade'
'huntsmade' anagrammed gives 'THEM AND US'.
(Other definitions for them and us that I've seen before include "workers' view of management?" , "adversarial situation" , "Opposites" , "Opposition parties" , "Two camps" .)
