Forced enemy to land (5)
I believe the answer is:
yemen
'to land' is the definition.
(Yemen is an example)
'forced enemy' is the wordplay.
'forced' is an anagram indicator.
'enemy' with letters rearranged gives 'YEMEN'.
(Other definitions for yemen that I've seen before include "Middle Eastern country" , "nation" , "Republic on the Arabian Peninsula" , "Country bordering Oman" , "Arab country" .)
