It brings about a military rising (8)
I believe the answer is:
reveille
This clue could be a double definition.
'it brings' is the first definition.
The definition suggests a singular noun which matches the answer.
'a military rising' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'about' is the link.
Can you help me to learn more?
(Other definitions for reveille that I've seen before include "Army waking signal" , "Military signal to wake up" , "Wake-up signal" , "The wake-up army bugle call" , "call to start" .)
