Two soldiers carrying medical officer in a US city (9)
I believe the answer is:
baltimore
'us city' is the definition.
(I've seen this before)
'two soldiers carrying medical officer in a' is the wordplay.
I cannot really see how this works, but
'soldiers' could be 're' (Royal Engineers) and 're' is found within the answer.
'officer' could be 'lt' (I've seen this in other clues) and 'lt' is found within the answer.
'a' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for baltimore that I've seen before include "US city" , "City of north Maryland" , "Port on Chesapeake Bay" , "City north-east of Washington DC" , "Largest city of Maryland, USA" .)
