Regarding the surname Korbut, understand that the suffix but means "to be." Is it correct that "kor" means "military" or "war?"

Thanks to advise the best translation: "in the military" "soldier?"

I have also read that that Korbut, Korbutas, Korybut was also a title adopted by some.

Thanks for your good comment.
