My heart smiles at the thought of the first crew to actually command this thing in a war zone pulling security on some unknown pile of rubble and being awoken at 0347 by their tank unexpectedly dumping its entire payload on an "enemy" that it hallucinated.
Granted, dumb privates do this too, but it's funnier to think about the tank doing it all by itself.
Imma get real pedantic here - "thermite" is just a composition, like C4, TNT, or PETN. Those drones show just one of many specific delivery methods, spraying or dropping pre-ignited thermite as they moves To say that "[thermite] sprays flammable liquid everywhere" isn't correct, but burning thermite can be spread like those drones do.
