Weapon choice should incorporate cover for the body (6)
I believe the answer is:
poncho
'cover for the body' is the definition.
'weapon choice should incorporate' is the wordplay.
'incorporate' indicates a hidden word (I've seen 'incorporates' mean this).
'PONCHO' is hidden in the letters of 'weapon choice should'.
(Other definitions for poncho that I've seen before include "Kind of cloak like blanket with slit for head" , "Blanket-like garment" , "A blanket-like cloak with a hole in the centre for the head" , "Type of cloak" , "South American garment" .)
