Enemy forced to land (5)
I believe the answer is:
yemen
'to land' is the definition.
(Yemen is an example)
'enemy forced' is the wordplay.
'forced' indicates anagramming the letters.
'enemy' with letters rearranged gives 'YEMEN'.
(Other definitions for yemen that I've seen before include "Republic sited on the SW corner of Arabia" , "Saudi neighbour" , "Aden is found here" , "Republic by the Red Sea" , "Country to south of Saudi Arabia" .)
