Team getting victory launched revolutionary air-to-air missile (10)
I believe the answer is:
sidewinder
'air-to-air missile' is the definition.
(type of missile)
'team getting victory launched revolutionary' is the wordplay.
'team getting' becomes 'side' (I am not sure about this - if you are sure you should believe this answer much more).
'victory' becomes 'win' (I've seen this before).
'launched' says the letters should be written backwards (in a down clue, letters get launched up).
'revolutionary' becomes 'red'.
'red' reversed gives 'der'.
'side'+'win'+'der'='SIDEWINDER'
(Other definitions for sidewinder that I've seen before include "Burrowing snake" , "1 of 21 [SNAKES] ?" , "Rattlesnake; misile" , "Rattlesnake with distinctive motion" , "Rattlesnake - air-to-air missile" .)
