Weapon; limb (3)
I believe the answer is:
arm
I believe this clue is a double definition.
'weapon' is the first definition.
(synonyms)
'limb' is the second definition.
(I know that arm is a type of limb)
(Other definitions for arm that I've seen before include "Prime" , "Accoutre" , "Activate warhead" , "Supply weapons" , "ready for war" .)
