Give weapons to a member (3)
I believe the answer is:
arm
I believe this clue is a double definition.
'give weapons' is the first definition.
(I've seen this in other clues)
'member' is the second definition.
(member can mean a limb)
'to a' is the link.
(Other definitions for arm that I've seen before include "strip of land?" , "inlet" , "Activate warhead" , "Shoulder to fingertip" , "Authority" .)
