I have no brilliant insight on this, I just find it interesting.
As the story goes, Ukrainian special forces are dropped of by a Blackhawk, then they get eliminated by FPV drones. See map for their movements.
As many commenters' my question is also what they wanted to achieve? Sure military history is full of miscalculation. What the higher command imagines what's going on there?

Related: heard on Fidesz/govt radio Ukraine collects various security forces, from military police to GRU and concentrates them near Pokrovsk. And even that Budanov himself controls the operations of them.
But how they put it I got the feeling that they are there to keep AFU units in check and in fighting in order. They did not say this, but I got this vibe. Perhaps they want to prevent a route and maybe even infiltrators to enter. They surely gained experience from previous important captures like Avdiivka, Velyke Novosilka, and the smaller ones (Bakhmut seemed different).
