The Digital and Intelligence Service (DIS) participated in the fifth edition of Defence Cyber Marvel (DCM), a multilateral cyber defence exercise conducted by the British Army Cyber Association. DCM brings together cyber defenders from various armed forces, government agencies and industry partners to learn, share best practices and strengthen collective cybersecurity capabilities in an evolving digital threat landscape. This year’s iteration of the exercise is held from 9 to 13 February 2026 in Singapore, with over 2,500 personnel from 29 nations participating in either Singapore or remotely around the world.

Forming a combined cyber defence team, the DIS’s Defence Cyber Command and its British Armed Forces counterparts will defend against a series of complex, real-world cyber threats simulated in a realistic operational environment. The team will respond to a range of simulated attacks targeting critical infrastructure, government networks, and private sector systems, gaining realistic experience in countering Advanced Persistent Threat actors amid a rapidly evolving digital and cyber-security landscape.

Senior Lieutenant-Colonel Mok Chuan-Hao, Commander, Cyber Defence Group, said, “This exercise offers us a valuable opportunity to learn from different nations and enhance our cyber defence capabilities in the face of complex, ever-evolving digital threats. The close collaboration with our UK partners will strengthen our shared cyber resilience and position Singapore as a key gateway for future cyber exercises in this region.”

Air Marshal Suraya Marshall, Deputy Commander of Cyber and Specialist Operations Command, said, “DCM 2026 places cooperation and shared learning at its heart. With cyber-attacks from our adversaries now a daily threat to the UK and our allies and partners, this exercise builds relationships and shared procedures essential for responding to cross-border threats.” She added, “Singapore's position as a leading technology and security hub makes it an ideal location for an exercise of this scale. The choice to hold the exercise in Singapore underscores the strategic importance of the Indo-Pacific region and the UK's ongoing work to strengthen cyber defence partnerships. This work also complements our NATO commitments by building a broader network of allies capable of responding to global threats.”

The DIS has participated in DCM since 2024, highlighting the growing importance of cybersecurity in modern military operations. The DIS’s consistent participation in this exercise with the British Armed Forces underscores the warm and long-standing bilateral defence relations between Singapore and the United Kingdom.
