I believe the answer is:

pin-ups

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

'girls' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'admired by the troops though stuck up' is the wordplay.
I cannot really understand how this works, but
'up' is present in the answer.
The remaining letters 'pins' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for pin-ups that I've seen before include "Cover girls" , "They may be very pretty" , "Posters of stars" .)
