Incline to get members a drill order (5,4)
I believe the answer is:
slope arms
'a drill order' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'incline to get members' is the wordplay.
'incline' becomes 'slope' (synonyms).
'to get' is a charade indicator (letters next to each other).
'members' becomes 'arms' (arm is a kind of member).
'slope'+'arms'='SLOPE ARMS'
Can you help me to learn more?
(Other definitions for slope arms that I've seen before include "Inclination members" , "Put rifle on shoulder" , "military command" .)
