Conclusion
It is hard to exactly tell how many vehicles are located between Komsomolske and Telmanove, but there are a lot and they are getting trained.
They could be used to force a breakthrough south of Volnovakha and north of Mariupol, as to bypass Mariupol and surround it in the next offensive.

UPDATE
