In order to enhance the effectiveness of suicide drones attacking bunkers, Russian soldiers removed the thermobaric warhead from an RPO-A "Bumblebee" rocket launcher and prepared to modify the fuse for use with a suicide drone.
This single-use thermobaric rocket launcher developed by the former Soviet Union in the 1980s is still widely used in the Russian military. This thing is very suitable for attacking bunkers; the explosion effect of the thermobaric warhead is better in enclosed and semi-enclosed spaces. The high-temperature explosive effect it generates can eliminate all living things inside the bunker.
