Russian troops fighting in Ukraine are likely suffering from a shortage of drinking water because of the damage inflicted by Moscow's strikes on Ukraine's infrastructure and compounded by high temperatures, British intelligence said in its daily report on August 13. It mentioned a Russian military blogger's claim on July 23 that water rations for Russian pilots had been limited to 1 liter per day -- a quarter of the minimum intake recommended for working in high temperatures. Some Russian units have been forced to drink water filtrated from stagnant puddles, thus increasing the risk of waterborne diseases, it said.
