Thousands of British Armed Forces personnel will remain deployed or on standby worldwide on Christmas Day, underscoring the UK’s continued military commitments at home and abroad amid heightened global security tensions.
The Ministry of Defence confirmed that service members from the British Army, Royal Navy and Royal Air Force will continue operations across Europe, the Middle East, the Indo-Pacific, Africa, the Caribbean, British Overseas Territories and UK waters throughout the festive period.
NATO deployments in eastern Europe
In Europe, around 900 British Army personnel remain deployed in Estonia and Poland as part of NATO’s Forward Land Forces, a key deterrence mission aimed at reassuring allies on the alliance’s eastern flank following Russia’s invasion of Ukraine.
RAF Typhoon jets are also flying NATO air policing missions over Poland under Operation Eastern Sentry, launched earlier this year after Russian drones breached Polish and Romanian airspace. The UK presence forms part of wider efforts by NATO to strengthen air defence and regional security.
Meanwhile, approximately 260 British troops continue to support the UN peacekeeping mission in Cyprus, marking 60 years of UK involvement along the island’s Green Line, one of the longest-running peacekeeping deployments in the world.
Middle East operations continue
The Royal Navy maintains a continuous presence in the Middle East, operating across the Gulf and Indian Ocean to support maritime security and regional stability. During 2025, UK naval forces intercepted multiple drug smuggling operations, seizing narcotics valued at more than £65 million.
British forces also remain deployed in Iraq at the invitation of the Iraqi government, supporting efforts to counter Daesh. RAF aircraft based at Akrotiri in Cyprus continue to conduct surveillance, reconnaissance and, when required, strike missions in support of Iraqi Security Forces.
In parallel, a small UK planning team remains embedded within the US-led Civil-Military Coordination Centre focused on post-conflict stabilisation planning for Gaza, reflecting Britain’s role in international security coordination in the region.
Indo-Pacific forward presence
In the Indo-Pacific, HMS Spey and HMS Tamar continue patrols under Operation Highwall as part of the Royal Navy’s forward deployment strategy. The mission supports freedom of navigation, maritime security and defence engagement with regional partners.
British Army deployments in the region exceed 900 personnel, including troops based in Brunei with the Royal Gurkha Rifles. Alongside military readiness, forces are involved in training exercises and community engagement with partner nations.
Africa and Caribbean missions
Across Africa, the British Army maintains a permanent presence in Kenya through the British Army Training Unit Kenya, a vital hub for preparing troops for operations in challenging environments. UK personnel are also deployed in Somalia, providing training, medical support and counter-IED assistance to UN, African Union and Somali National Army forces.
In the Caribbean, HMS Trent has taken over duties from HMS Medway as part of the Royal Navy’s standing commitment. The ship recently supported recovery efforts in Jamaica following Hurricane Melissa, highlighting the UK’s role in disaster response.
British forces also remain stationed in Overseas Territories including Gibraltar and the Falkland Islands, maintaining security and deterrence more than 40 years after the Falklands conflict.
Defence of UK waters and airspace
Closer to home, Royal Navy vessels, Fleet Air Arm helicopters and Royal Fleet Auxiliary ships will continue monitoring Russian naval activity around UK waters, which defence officials say has increased significantly in recent years.
RAF Quick Reaction Alert remains active 24 hours a day, with Typhoon jets on standby at RAF Lossiemouth and RAF Coningsby to intercept unidentified aircraft. RAF Poseidon maritime patrol aircraft will continue surveillance missions, while transport aircraft and helicopters remain ready to respond to domestic emergencies.
Cyber and homeland readiness
Behind the scenes, cyber specialists at MOD Corsham will remain on duty throughout Christmas, defending UK defence networks against cyber threats. Troops across the country will also stay on ceremonial and operational standby, ensuring that national security responsibilities continue uninterrupted during the holiday period.
The continued global deployment reflects the UK’s defence posture under its integrated review, which prioritises NATO commitments, deterrence against state threats and readiness to respond to crises worldwide.
