The country is divided into three areas for administrative and operational reasons, and in each area there is an infantry Brigade. The three brigade group structure envisages distinct operational areas of responsibility for each of the brigades and is supported in their responsibilities by the Naval Service and Air Corps. Each of the Brigade formations and the Air Corps are commanded by a Brigadier General while the Naval Service is commanded by a Commodore.
