Impact of wind on fighting service (3-5)

Ross

I believe the answer is:

air-force

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

'service' is the definition.
(I know that air force is a type of service)

'impact of wind on fighting' is the wordplay.
I cannot quite see how this works, but
'impact' could be 'force' and 'force' is present in the answer.
'wind' could be 'air' (air is a kind of wind) and 'air' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...

Can you help me to learn more?
