Some pilot or soldier’s dismembered body (5)
I believe the answer is:
torso
'dismembered body' is the definition.
(central part of body excluding limbs and head)
'some pilot or soldier's' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'TORSO' can be found hidden inside 'pilot or soldiers'.
(Other definitions for torso that I've seen before include "Body without head, neck and limbs" , "Poorly-dressed child" , "part of body will be found" , "Body's core" , "Roost on trunk?" .)
