On roll call for military revolution? (5-4)
I believe the answer is:
about-turn
'military revolution' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'on roll call' is the wordplay.
'on' is a charade indicator (letters next to each other).
'roll' becomes 'turn' (turn can mean to roll over).
'call' becomes 'about' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'turn' put after 'about' is 'ABOUT-TURN'.
'for' is the link.
Can you help me to learn more?
(Other definitions for about-turn that I've seen before include "Change of opinion" , "Total change of direction" , "Act of pivoting 180 degrees" .)
