'recon missions heard' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'you are in new shift on sunday' is the wordplay.
'you' becomes 'u' (I've seen this in other clues).
'are in' means one lot of letters goes inside another.
'new' indicates anagramming the letters.
'on' means one lot of letters go next to another.
'sunday' becomes 's'.
'shift' is an anagram of 'shfti'.
'u' put inside 'shfti' is 'shufti'.
'shufti'+'s'='SHUFTIS'
