Shade providing cover for troops? (5)

I believe the answer is:

khaki

I'm a little stuck... Click here to teach me more about this clue!

'shade' is the definition.
(I know that khaki is a colour)

I don't understand how the remainder of the clue works.

(Other definitions for khaki that I've seen before include "Military camouflage colour" , "Military uniform cloth - colour" , "Dark green colour" , "Dull brownish" , "Dust-coloured" .)

I've seen this clue in The Times.
