The head of the British army, Gen. Patrick Sanders, has warned that U.K. civilians should be prepared to fight in a hypothetical land war, citing the ongoing Russian invasion of Ukraine. He emphasized the importance of citizen armies in conflicts and stated that the British military is currently too small to respond to emerging threats. Sanders called for an increase in military spending and a standing force of around 120,000 soldiers by 2027. The U.K. government ruled out military conscription in response to his remarks. Other defense officials have also expressed concerns over growing international threats, including Russia. NATO has begun its largest war games since the Cold War, involving about 90,000 troops from allied nations. Dutch Adm. Rob Bauer, the NATO military committee chief, urged citizens to prepare basic supplies in case of unexpected conflict.
