Army scout redeployed, as per standard practice (9)
I believe the answer is:
customary
'per standard practice' is the definition.
I can't judge whether this defines the answer.
'army scout redeployed' is the wordplay.
'redeployed' indicates an anagram.
'army'+'scout'='armyscout'
'armyscout' with letters rearranged gives 'CUSTOMARY'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for customary that I've seen before include "Normal, usual" , "precedent" , "Commonly used or practised" , "Courts may find this usual" , "Conventional" .)
