Not necessarily. The result sounds a lot like the resulting effect from an Israeli Rafeal *Spike-3* ATGM launcher missile hit. They're capable of either *fire and forget* attacks up close, or guided top-attack hits out to 4 KM when under operator guidance till impact; the NunTet-Dandy version is said to achieve hits out to 7.5 KM. And the Israelis know how to build weapons for killing tanks, even an Abrams. The things have been sold to Indonesia, Singapore and Finland, possibly others including Estonia and Serbia, and there's always the possibility that the Jihidists managed to divert one or more directly from Israel via Jordan.
