Clandestine soldier (7)

I believe the answer is:

private

I believe this clue is a double definition.

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

'soldier' is the second definition.
(private is a type of soldier)

(Other definitions for private that I've seen before include "Clandestine" , "Secret - serviceman" , "Not openly shared" , "'Saving - - Ryan' (film)" , "Lowly soldier" .)

I've seen this clue in The Sun.
