... helping what current soldiers are doing? (7)

I believe the answer is:

serving

This clue is a double definition.

'helping' is the first definition.
(a helping is a serving of food)

'what current soldiers are doing?' is the second definition.
(serving in the army)

(Other definitions for serving that I've seen before include "Portion of food - being useful" , "Quantity of food for one person" .)

I've seen this clue in The Telegraph.
