Having members carrying weapons (5)
I believe the answer is:
armed
This clue is a double definition.
'having members' is the first definition.
(arms are limbs or members)
'carrying weapons' is the second definition.
(someone carrying a weapon is armed)
(Other definitions for armed that I've seen before include "brachiate?" , "Having guns" , "equipped for fighting" , "Munitioned" , "prepared to shoot?" .)
