The Singapore Armed Forces (SAF) is the military arm of the Total Defence of the Republic of Singapore; as well as the military component of the Ministry of Defence. The SAF has three services: the Singapore Army, the Republic of Singapore Air Force (RSAF) and the Republic of Singapore Navy (RSN). The SAF protects the interests, sovereignty and territorial integrity of Singapore from external threats. The SAF is to deter aggression, and should deterrence fail, to secure a swift and decisive victory. In peacetime, the SAF is to be ready and capable of conducting a spectrum of operations to protect our national interests and the well-being of Singapore's citizens.
