Warrant to arrest or set about soldiers (11)
I believe the answer is:
endorsement
'warrant' is the definition.
(I know that warrant can be written as endorsement)
'arrest or set about soldiers' is the wordplay.
I cannot really understand how this works, but
'or' is within the answer.
'soldiers' could be 'men' (men can mean a group of soldiers) and 'men' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for endorsement that I've seen before include "Approval - modern teens (anag)" , "passing through red light may carry it" , "Support and approval" , "okay?" , "Public approval" .)
