Ground patrols round a country (8)
I believe the answer is:
pastoral
'country' is the definition.
(I've seen this before)
'ground patrols round a' is the wordplay.
'ground' indicates anagramming the letters ('grind' the letters into a new form).
'round' indicates putting letters inside.
'patrols' is an anagram of 'pastorl'.
'pastorl' placed around 'a' is 'PASTORAL'.
(Other definitions for pastoral that I've seen before include "of a priest" , "Idyllic" , "Relating to the countryside or shepherds" , "to do with priestly duties" , "Portraying romanticised country life" .)
