It’ll keep you covered in location of ultimate defeat? (6,3)
I believe the answer is:
cocked hat
'defeat?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cocked hat that I've seen before include "Military cover" , "one may knock into" , "Triangular headgear, pointed at front and back" , "capital investment" .)
