Soldier quick to learn about unserviceable gear (9)

Ross

I believe the answer is:

apparatus

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

'gear' is the definition.
(I've seen this before)

'soldier quick to learn about unserviceable' is the wordplay.
'soldier' becomes 'para' (para is a kind of soldier).
'quick to learn' becomes 'apt' (I can't explain this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'unserviceable' becomes 'us' (abbreviation).
'para' put within 'apt' is 'apparat'.
'apparat'+'us'='APPARATUS'

Can you help me to learn more?

(Other definitions for apparatus that I've seen before include "Tackle" , "Technical equipment" , "Piece of equipment" , "Equipment, device" , "Equipment, gear" .)
