Drill order fast over a month (5,5)
I believe the answer is:
quick march
'drill order' is the definition.
'quick march' can be an answer for 'order' (I've seen this before). I am unsure of the 'drill' bit.
'over a month' is the wordplay.
'over' becomes 'quick' (I can't explain this - if you can you should believe this answer much more).
'a month' becomes 'March' (March is an example).
'quick'+'march'='QUICK MARCH'
'fast' is the link.
Can you help me to learn more?
(Other definitions for quick march that I've seen before include "may be part of a tattoo?" , "Order for soldiers to move" , "Military movement order (to foot soldiers?)" , "Military command (to step on it!)" .)
