Ordered most of team to get into action (7)
I believe the answer is:
decreed
'ordered' is the definition.
(I've seen this before)
'most of team to get into action' is the wordplay.
'most of' means to remove the last letter.
'team' becomes 'crew' (crew is a kind of team).
'to get into' indicates putting letters inside.
'action' becomes 'deed' (deed is a kind of action).
'crew' with its final letter removed is 'cre'.
'cre' going within 'deed' is 'DECREED'.
(Other definitions for decreed that I've seen before include "Ordained" , "Officially ordered" .)
