This sounds the same as Napalm to me. And I thought that was banned. OK if Ukraine does it I guess.
Nothing like napalm, but hey Russian has been using phosphorus shells on civilians for years
So OK if Russians do it ?😎
Thermite is some nasty stuff. Back in the day (Navy, 70s-early 80s) we always had a flat-pack of Thermite in any safe that contained classified material. In the event of potential attack or overrun one would pull the igniter cord on the pack and it would destroy everything in the safe in about 10 seconds. Depending on the container, it would also destroy the safe... Nasty stuff.
