That's the equipment man (3)
I believe the answer is:
kit
I believe this clue is a double definition.
'that's the equipment' is the first definition.
(kit is a kind of equipment)
'man' is the second definition.
(Other definitions for kit that I've seen before include "tackle" , "Equipment, clothing" , "Set - uniform - gear" , "Apparatus" , "Set of articles or tools" .)
