Bintang Temasek
The Bintang Temasek is the most prestigious of Singapore's national honours, established on 24 July 1970. It is conferred solely upon members of the Singapore Armed Forces, the Singapore Police Force or the Singapore [Civil Defence Force] who have demonstrated acts of exceptional courage and skill, or have shown conspicuous devotion to duty in circumstances of extreme danger. The decoration may be awarded posthumously, and recipients are entitled to use the post-nominal letters BT.
Since its institution, no individual has yet received the Bintang Temasek. The insignia is to be worn on the left side of the outer garment, suspended from a ribbon. It remains the highest recognition for valour or devotion to duty in the face of extraordinary peril within Singapore's uniformed services.
