Advantaged with transport (3)
I believe the answer is:
van
'transport' is the definition.
(van is a kind of transport)
'advantaged with' is the wordplay.
'with' indicates a hidden word.
'VAN' is hidden within 'advantaged'.
(Other definitions for van that I've seen before include "Commercial vehicle or front of army" , "Leading military units" , "Leading group" , "Commercial vehicle in the lead?" , "Leading part" .)
