Footage claims to show a Russian Spetsnaz team utilizing a 9M133 Kornet, presumably against Ukrainian armor.

One interesting thing to note from this footage is when the missile strikes its intended target, a large sonic blast spans a vast area, leaving a very different explosion compared to the Ukrainian Stugna-p. Although the Stugna-p and Kornet fall into the same category of anti-tank weapon systems, the Kornet has the capability to fire thermobaric warheads. With that information and watching the provided footage, it would appear this Kornet was equipped with a thermobaric missile during this firing sequence.

Regardless, whatever target was hit by this missile had to have sustained a catastrophic fate.
