Divisional leader wants support of course, guarding RAF conscript (7)
I believe the answer is:
draftee
'conscript' is the definition.
('draftee' can be a synonym of 'conscript')
'divisional leader wants support of course guarding raf' is the wordplay.
'leader' suggests taking the first letters.
'wants' means one lot of letters go next to another.
'support of course' becomes 'tee' (support for ball on golf course).
'guarding' is an insertion indicator.
The first letter of 'divisional' is 'd'.
'd'+'tee'='dtee'
'dtee' going around 'raf' is 'DRAFTEE'.
(Other definitions for draftee that I've seen before include "US conscript" , "Rookie" , "one brought into service" , "American military conscript" , "Soldier, perhaps unwilling" .)
