Food for new recruits (6)
I believe the answer is:
intake
This clue is a double definition.
'food' is the first definition.
(food taken into the body)
'new recruits' is the second definition.
(I've seen this before)
'for' is the link.
(Other definitions for intake that I've seen before include "Number of acceptances as in school" , "new kids?" , "Consumption" , "New recruits" , "Air inlet of jet engine" .)
