Conveyance for soldiers arrives in Rio -- copter, possibly (5,7)

I believe the answer is:

troop carrier

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

'conveyance' is the definition.
(troop carrier is a kind of conveyance)

'arrives in rio copter possibly' is the wordplay.
'arrives' becomes 'arr' (abbreviation used in transport).
'in' is an insertion indicator.
'possibly' indicates an anagram.
'rio'+'copter'='riocopter'
'riocopter' is an anagram of 'troopcier'.
'arr' placed into 'troopcier' is 'TROOP-CARRIER'.

'for soldiers' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for troop carrier that I've seen before include "Ship transporting armed forces" , "Military vehicle" .)

I've seen this clue in The Telegraph.
