One who endures being a carrier of equipment? (6)
I believe the answer is:
bearer
I believe this clue is a double definition.
'one who endures' is the first definition.
(someone who bears things)
'a carrier of equipment?' is the second definition.
(bear can mean to carry)
'being' is the link.
(Other definitions for bearer that I've seen before include "He helps to carry something - sometimes a coffin" , "One who carries, maybe a coffin" , "One who helps to carry something - maybe news" , "He carries something, stretcher or news" , "Carrier to whom cheque may be payable" .)
