Recon specialist ditching uniform and ID holder outside Germany's police HQ (8,4)
I believe the answer is:
scotland yard
'police hq' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for scotland yard that I've seen before include "Detective department of the Metropolitan Police" , "London CID" , "Metropolitan Police HQ" , "detectives" , "(New) office for the Met" .)
