Serviceman captures a foul-mouthed nationalist (9)

Ross

I believe the answer is:

garibaldi

I'm a little stuck... Click here to teach me more about this clue!

'nationalist' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?

'serviceman captures a foul-mouthed' is the wordplay.
'serviceman' becomes 'gi' (informal term for a US soldier).
'captures' means one lot of letters goes inside another.
'foul-mouthed' becomes 'ribald' (I've seen this before).
'a'+'ribald'='aribald'
'gi' enclosing 'aribald' is 'GARIBALDI'.

Can you help me to learn more?

(Other definitions for garibaldi that I've seen before include "Currant sandwich biscuit" , "military commander" , "leader of nationalists" , "Italian leader; biscuit" , "Lady's blouse" .)
