The Singapore Volunteer Corps or the Singapore Special Constabulary, was a militia unit established in 1854 as the Singapore Volunteer Rifle Corps. The Corps underwent several reorganisations and was known by various names throughout its history. It was renamed the People's Defence Force, the predecessor of the Singapore Armed Forces (SAF) in 1965.

The Singapore Armed Forces (SAF) are the military of the Republic of Singapore, responsible for protecting and defending the security interests and the sovereignty of the country. A component of the Ministry of Defence (MINDEF), the armed forces have four service branches: the Army, Navy, Air Force, and Digital and Intelligence Service. An integrated force, it is one of the most capable, robust, technologically sophisticated and powerful militaries in the Southeast Asia region. The SAF is headed by the chief of defence force, appointed by the President, on the advice of the Cabinet.
