Drone can put out weapons (8)
I believe the answer is:
ordnance
'weapons' is the definition.
(I've seen this before)
'drone can put out' is the wordplay.
'put out' indicates an anagram.
'drone'+'can'='dronecan'
'dronecan' is an anagram of 'ORDNANCE'.
(Other definitions for ordnance that I've seen before include "The Survey provides maps" , "type of armament" , "Arsenal's big guns" , "Mounted guns, cannon" , "Anne Cord is in military supplies" .)
