American soldier reversing in vehicle that produces smoke (5)
I believe the answer is:
cigar
'produces smoke' is the definition.
'cigar' can be an answer for 'smoke' (smoke can mean a cigar). I am not sure about the 'produces' bit.
'american soldier reversing in vehicle' is the wordplay.
'american soldier' becomes 'GI' (informal term for a US soldier).
'reversing' says the letters should be written in reverse.
'in' is an insertion indicator.
'vehicle' becomes 'car' (car is a kind of vehicle).
'gi' in reverse letter order is 'ig'.
'ig' put within 'car' is 'CIGAR'.
'that' is the link.
Can you help me to learn more?
(Other definitions for cigar that I've seen before include "Corona, eg" , "Havana, say" , "Smoked item" , "A roll of leaf tobacco" , "Rolled tobacco leaf for smoking" .)
