Everyone round crazy cadet got assigned (9)
I believe the answer is:
allocated
'assigned' is the definition.
(allocating is a kind of assigning)
'everyone round crazy cadet' is the wordplay.
'everyone' becomes 'all' (all people).
'round' becomes 'o' (round can mean a round object).
'crazy' indicates an anagram.
'cadet' is an anagram of 'cated'.
'all'+'o'+'cated'='ALLOCATED'
'got' is the link.
(Other definitions for allocated that I've seen before include "Apportioned" , "set aside" , "Assigned" .)
