Field marshal (or field-marshal, abbreviated as FM) (UK pronunciation: i/fiːldˈmɑːʃəl/, US pronunciation: i/fildˈmɑːrʃəl/) is a very senior military rank, ordinarily senior to the general officer ranks. Usually it is the highest rank in an army, and when it is, few (if any) persons are appointed to it. It is considered as a five-star rank (OF-10) in modern-day armed forces in many countries.
