Man in red suit drops off US gunners in city there (5,5)
I believe the answer is:
santa clara
'us gunners in city there' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'man in red suit drops' is the wordplay.
'man in red' becomes 'santa' (I've seen this in another clue).
'suit drops' becomes 'clara' (I can't explain this - if you can you should believe this answer much more).
'santa'+'clara'='SANTA CLARA'
'off' is the link.
Can you help me to learn more?
(Other definitions for santa clara that I've seen before include "city" , "somewhere in California" .)
