• Singapore hosts DCM 2026 for first time
• Exercise aligns with UK Strategic Defence Review
• Private sector partners test emerging cyber technologies
• Builds Indo‑Pacific cyber cooperation and NATO links

Pulse Analysis

The Defence Cyber Marvel (DCM) 2026 marks the most expansive multinational cyber‑defence drill to date, gathering over 2,500 participants from 29 countries in a week‑long simulated conflict. By situating the exercise in Singapore, the United Kingdom signals a strategic pivot toward the Indo‑Pacific, a region increasingly contested by state‑backed hackers and supply‑chain vulnerabilities. The hub’s advanced digital infrastructure and status as a security nexus enable realistic threat modeling that mirrors the tactics of sophisticated adversaries. This geographic shift also deepens the UK‑Singapore strategic partnership, reinforcing diplomatic and economic ties through shared cyber resilience.

DCM 2026 pits blue and red teams against each other under a central command, replicating the decision‑making pressure of real‑world incidents. Military units from the Army, Royal Air Force and Royal Navy operate side‑by‑side with industry partners, testing emerging technologies on both conventional IT systems and complex industrial control environments. The drill directly supports the UK’s Strategic Defence Review, which prioritises war‑fighting readiness and the newly formed Defence Cyber & Electromagnetic Force. Participants sharpen technical skills, forge interoperable procedures, and generate actionable lessons that can be transferred to operational theatres across NATO and allied forces.

The exercise’s emphasis on public‑private collaboration signals a broader shift toward ecosystem‑wide cyber resilience. By exposing commercial vendors to high‑intensity scenarios, DCM accelerates the maturation of defensive tools that can be deployed across critical infrastructure. Moreover, the visibility of the drill enhances recruitment pipelines such as the Defence Digital & Cyber Bursary and Cyber Direct Entry schemes, feeding talent into the Defence Cyber & Electromagnetic Force. As cyber threats continue to blur geographic boundaries, the UK’s ability to convene multinational teams in Singapore positions it as a pivotal hub for future collective defence initiatives.

Defence Cyber Marvel 2026 · A Global Exercise to Strengthen International Cyber Defence · More than 2, 500 personnel from 29 countries to combat borderless cyber threats in a simulated environment. · Demonstrates international collaboration, essential for effective cyber defence in real‑world scenarios. · Exercise tests ability to coordinate international responses in a realistic operational environment, with scenarios mirroring genuine cyber threats.

The week‑long exercise will bring together more than 2,500 personnel from 70 different organisations and 29 countries to form 36 teams, including representatives from UK Defence and other UK Government departments such as the National Crime Agency, the Department for Work and Pensions, the Cabinet Office and the Department for Business and Trade.

Following the success of last year’s exercise in the Republic of Korea, Singapore will serve as the exercise hub for the first time, reflecting the UK’s commitment to deepening cooperation with Indo‑Pacific partners on shared security challenges.

The exercise demonstrates the practical value of real‑life scenarios, reinforcing international partnerships and directly supporting the Strategic Defence Review’s (SDR) ambition to shift to war‑fighting readiness by building a lethal, integrated force.

British High Commissioner to Singapore, Nik Mehta

“This year’s Defence Cyber Marvel showcases the deep cooperation between the UK and trusted partners like Singapore — a powerful reminder of the strength of our Strategic Partnership. In an increasingly turbulent and complex security landscape, we recognise the need to build a safer, more resilient digital domain.

What makes this exercise truly valuable is the chance for our personnel to forge real connections — trust, shared understanding, and professional friendships that form the backbone of our Strategic Partnership.

We’re grateful to Singapore for enabling us to host this global exercise here. It brings together UK, Singaporean, and international teams to exchange cyber expertise, sharpen the skills of our next generation, and deepen the cooperation that drives our long‑term digital and economic growth. I wish all participants a rewarding experience and look forward to hearing about their successes.”

Now in its fifth year, DCM has evolved from an Army Cyber Association initiative into a tri‑service operation led by Cyber and Specialist Operations Command (CSOC). This year’s exercise will test participating nations’ ability to coordinate responses in a realistic operational environment, with scenarios mirroring genuine cyber threats.

“DCM 2026 places cooperation and shared learning at its heart. With cyber‑attacks from our adversaries now a daily threat to the UK, our allies and our partners, this exercise builds relationships and shared procedures essential for responding to cross‑border threats.

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.”

Featuring several distinct storylines, the exercise is split between blue and red teams, controlled from a central command point. Key elements within the storylines include understanding the impacts of cyber scenarios and how escalating pressure leads commanders and teams to make different decisions on the ground.

With industry partners taking part alongside military personnel, DCM 2026 also showcases how Defence works with the private sector to develop emerging technologies in a controlled environment where they can be stress‑tested against realistic threat scenarios.

DCM 2026 provides a platform to highlight the professional cyber development opportunities available across UK Defence. Personnel operate under a realistic, pressured environment containing traditional IT systems as well as more complex industry control systems; decision‑making and technical skills can be transferred directly to operational settings, helping defend networks and disrupt daily attacks from UK adversaries.

Under the SDR, the Ministry of Defence has prioritised these critical skills. Investment in the Defence Digital & Cyber Bursary Scheme and the Cyber Direct Entry scheme offers new opportunities for applicants to develop and fast‑track their careers into Defence.

These programmes, together with the recently announced Defence Gap Year, Defence STEM & Undergraduate Scheme (DSUS), and Technical Defence Graduate and Apprenticeship schemes, support the Strategic Defence Review to create new entry routes into Defence careers.

The recent stand‑up of the Defence Cyber & Electromagnetic Force (DCEMF), led by Air Vice‑Marshal Tom Ashbridge, further delivers on the Strategic Defence Review as a new force safeguarding military operations in cyberspace by bringing together military personnel, defence companies and cyber teams.
