Carped absurdly, as a military police officer (6)
I believe the answer is:
redcap
'a military police officer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'carped absurdly' is the wordplay.
'absurdly' indicates an anagram.
'carped' anagrammed gives 'REDCAP'.
'as' is the link.
Can you help me to learn more?
(Other definitions for redcap that I've seen before include "MP" , "Military policeman (slang)" , "Mil. policeman (colloq.)" , "Goldfinch" , "Hole from explosion" .)
