Protection a European’s given to soldiers from another continent (5)
I believe the answer is:
aegis
'protection' is the definition.
('aegis' can be a synonym of 'protection')
'a european's given to soldiers from another continent' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'given to' says to put letters next to each other.
'soldiers from another continent' becomes 'gis' (GI can mean an American soldier).
'a'+'e'+'gis'='AEGIS'
(Other definitions for aegis that I've seen before include "Friendly endorsement and guidance" , "Protection (originally of Zeus)" , "Protection - guardianship" , "Advocacy" , "Protection (of someone)" .)
