Britain should train and equip its citizens to be ready to fight a war with Russia, the head of the army said, as Sweden has warned its citizens to brace for possible conflict with Moscow. 

Gen. Sir Patrick Sanders, the outgoing Chief of the General Staff, warned that an increase in reserve forces alone “would not be enough” to fight a land war with Russia, the BBC reported. He said increasing the number of soldiers for a potential conflict would need to be a “whole-of-nation undertaking.”

Sanders spoke of the need for the United Kingdom to maintain its military and cited the threat faced by other nations closer to Russia as Moscow continues its war with Ukraine. 

The commander in chief of the Swedish armed forces, General Micael Byden, who visited the eastern front of Ukraine in December, also spoke to the conference on Sunday, warning all Swedes to prepare mentally for the possibility of war as their nation is just two steps short of NATO membership.
