Soldiers new in Palestinian area must get material (7)
I believe the answer is:
organza
'material' is the definition.
(organza is a kind of material)
'soldiers new in palestinian area' is the wordplay.
'soldiers' becomes 'or' (Other Rank).
'new' becomes 'n'.
'in' indicates putting letters inside.
'palestinian area' becomes 'gaza' (I've seen this before).
'n' put into 'gaza' is 'ganza'.
'or'+'ganza'='ORGANZA'
'must get' acts as a link.
(Other definitions for organza that I've seen before include "Transparent silky material" , "Silk (or silk-like) fabric" , "Stuff" , "Thin material" , "dress material" .)
