More UK families will know what sacrifice for our nation means as the nation seeks to deter a potential confrontation with Russia, the head of the military has said. Sir Richard Knighton said the country's security cannot be outsourced to the armed forces and requires a whole-of-society response, including harnessing UK universities and manufacturing. While the chief of the defence staff suggested there was only a remote chance of Russia directly attacking the UK, he told an event at the Royal United Services Institute that so-called hybrid attacks showed the threat was worsening . He referenced a Russian spy ship that was recently suspected of mapping undersea cables near UK waters. Every day the UK is subject to an onslaught of cyber-attacks from Russia and we know that Russian agents are seeking to conduct sabotage and have killed on our shores, he added.
