 Although the primary role of the SMF is the internal and external security of Mauritius, it is also used in several other roles such as ceremonial guards of honour, search and rescue operations, bomb disposal, debris clearance and opening of roads after cyclones and other emergencies.The badge of the SMF is made up of a wreath of oak leaves surmounted by the national coat of arms.Within the wreath are the letters S and F, with a lightning flash between them, to symbolise the letters "SMF".
