Battle, project win! (7)
I believe the answer is:
jutland
'battle' is the definition.
(Jutland is an example)
'project win' is the wordplay.
'project' becomes 'jut' (project can mean to jut out).
'win' becomes 'land' (both can mean to secure or obtain).
'jut'+'land'='JUTLAND'
(Other definitions for jutland that I've seen before include "Peninsula in northern Europe" , "part of Denmark" , "WWI naval battle" , "World War I naval battle" , "battle in the main" .)
