US rifle I adapted for British soldier (8)
I believe the answer is:
fusilier
'british soldier' is the definition.
'fusilier' can be an answer for 'soldier' (fusilier is a kind of soldier). I'm not certain of the 'british' bit.
'us rifle i adapted' is the wordplay.
'adapted' indicates anagramming the letters.
'us'+'rifle'+'i'='usriflei'
'usriflei' anagrammed gives 'FUSILIER'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for fusilier that I've seen before include "Formerly a British infantryman" , "Soldier in an infantry regiment originally armed with light muskets" , "He used to be a British infantryman" .)
