Award soldiers capturing cape in South Africa (5)
I believe the answer is:
oscar
'award' is the definition.
(Oscar is an example)
'soldiers capturing cape in south africa' is the wordplay.
'soldiers' becomes 'or' (Other Rank).
'capturing' means one lot of letters goes inside another.
'cape' becomes 'c' (abbreviation used on maps).
'in' is an insertion indicator.
'south africa' becomes 'sa' (abbreviation).
'c' going into 'sa' is 'sca'.
'or' placed around 'sca' is 'OSCAR'.
(Other definitions for oscar that I've seen before include "US film award" , "Award by the Academy of Motion Picture Arts and Sciences" , "Title of Hollywood Academy award" , "Wildean film award?" , "Movie award, popularly called" .)
