Crack soldiers in Egypt emptied kit (9)
I believe the answer is:
equipment
'kit' is the definition.
(I've seen this before)
'crack soldiers in egypt emptied' is the wordplay.
'crack' becomes 'quip' (both can mean a joke).
'soldiers' becomes 'men' (I've seen this before).
'in' means one lot of letters goes inside another.
'emptied' suggests removing the centre.
'egypt' with its middle removed is 'et'.
'quip'+'men'='quipmen'
'quipmen' placed within 'et' is 'EQUIPMENT'.
(Other definitions for equipment that I've seen before include "outfit" , "fitting" , "Stuff" , "Apparatus, tools" , "Kit, apparatus" .)
