The rank derives from the (master specialist) rank that was originally available only in some branches of service. Early in the history of independent Finland's armed forces, graduates of the professional NCO school (see) were promoted to (sergeant first class) upon graduation, but could not be promoted further, which led to frustration among outstandingly competent NCOs. Because of this, the rank was made available to all branches, and renamed (sergeant major, 'master soldier' directly translated from Finnish). Furthermore, the rank of (master sergeant) was also introduced. A Finnish speciality was that was ranked higher in Finnish army than (second lieutenant) in peace time.
