I believe the answer is:

gig-lamps

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

'upmarket tent having old-fashioned specs' is the definition.
I know nothing about this answer so I can't tell whether this works.

'soldier' is the wordplay.
I cannot really understand how this works, but
'soldier' could be 'gi' (GI can mean a US soldier) and 'gi' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'uses' acts as a link.

Can you help me to learn more?
