Suriname deports US member of the corps (6)
I believe the answer is:
marine
'corps' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for marine that I've seen before include "Soldier serving on land and sea" , "Maritime - seagoing soldier" , "seaman" , "Concerned with the sea" , "Concerning the sea" .)
