Russian forces are running out of the critical radars they need to defeat Ukraine's artillery, UK intel says

• Both Ukraine and Russia rely on counter-battery radars to strike each other's artillery. 
• But Moscow's troops face a shortage of critical radars that has only worsened during the war. 
• Britain's defense ministry said Russian forces likely only have a few key systems remaining. 

Relentless and brutal artillery battles between Russian and Ukrainian forces are a key feature of ongoing fighting, leaving both sides dependent on counter-battery detection to find and attack enemy fire.
