From what I understand Putin is using a stricter definition of “cluster bombs” as a muntition containing a bomblets submunition.
I have seen of Russian videos munitions are hypersonic missiles, thermobaric bombs (incendiary submunition), and timed remote mine submunitions (a timed self-destruct feature or one that turns it inert after a while) but none utilizing a pressure fuse like the butterfly mines that were used by Ukraine.
They are terrible weapons regardless of definition
