Russian troops reportedly used anti-thermal cloaks to evade detection by surveillance drones equipped with thermal-imaging (TI) sensors, allowing them to penetrate Ukrainian lines in Krasnoarmeysk at night.
The troops entered Ukrainian-held territory despite the presence of enemy drones, ambushed equipment and personnel, and mined roads to cut off supply lines—leaving the adversary confused and disorganised.
The cloaks—nicknamed “anti-drone raincoats” due to their poncho-like design and waterproof qualities—incorporate insulating and reflective materials such as nylon with embedded aluminium or silver particles, or layered Mylar (a reflective foil-like material) sandwiched between fabric.
These “raincoats” prevent the escape of infrared (IR) radiation emitted by the human body, which TI sensors detect as heat signatures. Their outer surface remains close to ambient temperature, reducing the thermal contrast needed for TI detection.
They are particularly effective during “thermal crossover” periods, when air and ground temperatures are nearly equal. This typically occurs after daybreak and sunset, as well as in rain or fog. During the day, the raincoats can also be effective when troops remain close to objects such as rocks or vegetation that are warmer than the surrounding air.
