After sectarian conflict, dispatch part of army deployment (4-11)

I believe the answer is:

post-reformation

'after sectarian conflict' is the definition.

'dispatch part of army deployment' is the wordplay.
'dispatch' becomes 'post'.
'part of army' becomes 're' (I've seen this in other clues).
'deployment' becomes 'formation'.
'post'+'re'+'formation'='POST-REFORMATION'

(Another definition for post-reformation that I've seen is " following Thirty Years War?".)

I've seen this clue in The Times.
