Start fighting recruit (6)

I believe the answer is:

engage

I believe this clue is a double definition.

'start fighting' is the first definition.
(I've seen this before)

'recruit' is the second definition.
(I've seen this before)

(Other definitions for engage that I've seen before include "Employ or captivate" , "Take on (eg for work, in battle)" , "Take into employment or occupy attention" , "Employ, hire" , "Take on, hire" .)

I've seen this clue in The Telegraph.
