It is pretty obvious the problem here is cost. They are basically mounting Grad systems on pickup trucks.
This is similar to systems seen in Syria.
The video actually shows multiple systems. The legacy Grad, the Tornado-G, and newer systems which are meant to be cheaper and more mobile albeith with shorter range. The video shows the Grad and Tornado-G at times, but the topic it is talking about is the newer cheaper systems.

This system seems to be fully automated and digitized. It uses the newer short 122mm rockets. The thing is, with the increases in capability given to the Grad in its Tornado-G form with composite casing and more energetic propellant, this new system likely ends up having similar range and capabilities to the original Grad but can be placed in a much lighter weight platform. I mean just look at it, this is a two axle truck, instead of the three axle truck you typically see used with the Grad.
Then you have this system mounted on regular pickups, which looks similar to systems seen in Syria.

It is basically a way to provide cheap mobile harassment fire.
