First comment there answers your question:
If any body was wondering : The weapon used is a Ukrainian made ( by
State engineering firm Luch ) ATGM (Anti tank guided missile) called
Skif or Stugna ,it fires 130 or 155 mm anti ERA rockets and has
manual (by joystick) and "FF" laser guidance ( fire and forget)
system. The whole system weights about 100 KG and has a range about 5
km .The briefcase/ laptop control panel with the joystick is a PDU 215
which is attached by wire to the launcher.
Just out of curiosity what was the missile system in that YouTube video?
