WYTON, England —  Europe must be prepare for war on its doorstep, British military chiefs warned Thursday as they detailed an unprecedented level of threat against the U.K.’s armed forces.

Speaking at the launch of a new British Military Intelligence Service (MIS) Defense Minister Al Carns said the “shadow of war is knocking on Europe’s door” and warned NATO allies must be ready to respond.

Europe is not facing “wars of choice” anymore but “wars of necessity” which will come with a high human cost, Carns argued, citing Russia’s invasion of Ukraine as an example.

Hostile intelligence activity against British military personnel and property has risen by more than 50 percent over the last year, mainly coming from Iran, China and Russia, Chief of Defense Intelligence Adrian Bird revealed at the same launch event at Royal Air Force Wyton.

The RAF base in Cambridgeshire, in the east of England, will house the new unified intelligence service, and is already home to Pathfinder — the largest “five eyes” intelligence hub in the world.

MIS will bring together units from the Royal Navy, British Army and Royal Air Force in a bid to speed up information sharing, as recommended by this year’s Strategic Defense Review (SDR).

It will also host a new “Defence Counter-Intelligence Unit,” designed to protect the armed forces and their equipment and systems from foreign interference. 

Personnel at Wyton will monitor a wide range of data from satellite imagery and drone-recorded video footage, as well as information gathered by agents in the field.

Following a recent damning report into Britain’s preparedness for war by the U.K. House of Commons Defense Committee, Carns argued that revamping military intelligence will help ensure “that our deterrence is absolutely foolproof.”

Carns stressed the need to convince the British public of the seriousness of the threats posed by hostile states. Ministers need to “make sure the population recognize that those threats overseas have direct impacts to their way of living, their cost of living, food prices, fuel prices, and government spending as a whole,” he said.

His warnings echo those issued by NATO boss Mark Rutte, who said during a speech in Berlin on Thursday: “Russia has brought war back to Europe, and we must be prepared for the scale of war our grandparents and great grandparents endured.”

Senior figures overseeing the British launch admit they face a shortfall in recruiting people to intelligence roles. 

Minister for Veterans Louise Sandher-Jones told reporters: “We know over the past few years that [recruitment] has not gone in the direction that we wanted, and it’s definitely very much a mission for us to turn that around.”
