Soldier's new bride touring capital (9)
I believe the answer is:
brigadier
'soldier's' is the definition.
'new bride touring capital' is the wordplay.
'new' indicates anagramming the letters.
'touring' means one lot of letters goes inside another (touring can mean going round).
'capital' becomes 'riga' (Riga is an example).
'bride' anagrammed gives 'bdier'.
'bdier' enclosing 'riga' is 'BRIGADIER'.
(Other definitions for brigadier that I've seen before include "Military leader" , "Officer in charge of army unit, part of division" , "Rank above colonel" , "Air bridge over to the military officer" , "Army rank" .)
