This is a nice summary of Russian tactics.

The parts fit and roll well together.
- push on the flanks
- fatten the gains
- vertically envelope the ground between the flanks
- pin everyone in place with drones, they see every movement and can strike there, force the enemy to huddle in fortifications
- pound the fortifications with arty (and fabs), tear them up
- when the fortifications are broken and opened up, no sealed place to hide kill the living force with thermobarics
- move in with ground troops to kill or capture those who survived still, and occupy the place
I think DRGs aren't explained well, so a bit hard to fit them in. I think those are used to prod enemy lines and find the easiest way where they can open up a flank, and if there is a prolonged siege of one enveloped pocket they also sent to find way ins (and when inside they can act diversionary too). On the flanks they "overload" a place as infantry where other Russian elements can move in, such as drone teams. Then they try to build the "defensive bubble" of various weapon systems while they fatten the flank: pushing in heavy weaponry, air defense, EW equipment, etc.
From just this:
>to puncture pores lines, sow chaos, and accumulate forces
...it's hard to imagine what they really do and achieve (beyond dying or get captured).
The process above (push on flanks ... occupy) can be done on various scale. For example when they build a flank, they push out from the line, a bulge forms but two potential envelopments on both side. They can hold enemy in there with drones, drop some bombs them, maybe even use the tochka, then occupy that place to fatten the gains.
And for larger scale there is now Pokrovsk-Mirnograd as live example.
