Major-general
Major general (short MG or Maj. Gen) is a military rank used in many countries. It is derived from the older rank of sergeant major general. The disappearance of the "sergeant" in the title explains the apparently confusing phenomenon whereby a lieutenant general outranks a major general (although a major outranks a lieutenant, a lieutenant outranks a sergeant-major.)
In the Commonwealth and the United States, it is a division commander's rank subordinate to the rank of lieutenant general and senior to the rank of brigadier or brigadier general. In the Commonwealth, major general is equivalent to the navy rank of rear admiral, and in air forces with a separate rank structure, it is equivalent to air vice-marshal.
In some small countries, such as Estonia, major general is the highest rank currently used and in some countries, including much of Eastern Europe, major general is the lowest of the general officer ranks, with no brigadier-grade rank above colonel.
In the old Austro-Hungarian Army, the major general was called a Generalmajor. Today's Austrian Federal Army still uses the same term.
