Occasional soldiers - tiredness ends in scraps (8)
I believe the answer is:
oddments
'scraps' is the definition.
('oddment' can be a synonym of 'scrap')
'occasional soldiers tiredness ends' is the wordplay.
'occasional' becomes 'odd' (odd can mean occasional or infrequent).
'soldiers' becomes 'men' (men can mean a group of soldiers).
'ends' says to hollow out the word (remove centre letters).
'tiredness' with its centre removed is 'ts'.
'odd'+'men'+'ts'='ODDMENTS'
'in' is the link.
(Other definitions for oddments that I've seen before include "just a few items" , "Assorted leftovers" , "Mods tend to don bits and pieces" , "Motley assortment of things" , "Bits and pieces, isolated garments" .)
