Brigade's gear (3)
I believe the answer is:
rig
'gear' is the definition.
(rig is a kind of gear)
'brigade's' is the wordplay.
'RIG' is hidden within the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for rig that I've seen before include "Apparatus; fix" , "Put sails on" , "uniform perhaps" , "Oil platform" , "Set up; equipment" .)
