Soldier pulled up in vehicle for a smoke (5)
I believe the answer is:
cigar
'a smoke' is the definition.
(I've seen this before)
'soldier pulled up in vehicle' is the wordplay.
'soldier' becomes 'gi' (government issue or general issue).
'pulled up' is a reversal indicator.
'in' is an insertion indicator.
'vehicle' becomes 'car' (car is a kind of vehicle).
'gi' reversed gives 'ig'.
'ig' put inside 'car' is 'CIGAR'.
'for' is the link.
(Other definitions for cigar that I've seen before include "Havana, perhaps" , "Item for smoking" , "Corona, eg" , "Smoked item" , "Cylinder of tobacco" .)
