Soldat is the lowest rank of enlisted men in the armies of some countries.

In the land-based armed forces of Germany, Austria, Ukraine, and Switzerland it is usually grouped as OR-1 ([zɔlˈdaːt] short: S, plural Soldaten) within the NATO ranking system, excluding the Swiss armed services which does not follow NATO standards.

[1] The German term Soldat (equivalent to Soldier in English) has its roots as far back as the 16th-century, where it was a common designation for a paid or remunerated ordinary-rank member of a military infantry, especially one who was not an officer.

The sequence of ranks (top-down approach) in that particular group is as follows: The designation of the particular OR1-rank depends on the individual branch and career of the soldier as regulated in the Zentrale Dienstvorschrift 14/5.

The sole OR1-rank designation in the Marine is Matrose, and Sanitätssoldat in the Bundeswehr medical service.
