Ignore flying doctor giving war cry (8)
I believe the answer is:
geronimo
'war cry' is the definition.
(I've seen this before)
'ignore flying doctor' is the wordplay.
'flying' is an anagram indicator.
'doctor' becomes 'mo' (medical officer).
'ignore' anagrammed gives 'geroni'.
'geroni'+'mo'='GERONIMO'
'giving' is the link.
(Other definitions for geronimo that I've seen before include "C19 Apache chief" , "shout during dive" , "[APACHE] leader" , "Cry of exhilaration" , "I'm no ogre like famous Apache Indian chief" .)
