Force has ceremonial kit covering uniform (6)

I believe the answer is:
duress
'force' is the definition.
(duress is a kind of force)
'ceremonial kit covering uniform' is the wordplay.
I cannot quite see how this works, but
'uniform' could be 'u' (phonetic alphabet: alpha, bravo, charlie etc.) and 'u' is located in the answer.
'covering' could be 'dress' (dress is a kind of covering) and 'dress' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'has' is the link.
Can you help me to learn more?
(Other definitions for duress that I've seen before include "Excessive pressure" , "Constraint, coercion" , "Pressure (involving threats)" , "Threats, violence, etc, used in coercion" , "Use of force or threats, often vile" .)
