Guess the Propellant
https://www.rt.com/news/418519-russia-tests-interceptor-miss...
It looks like a copper thermite ignitor... with a overfueled hydrocarbon??

Looks to be a solid propellant mixture, very dirty engines, and are preferred for anti-ballistic missiles due to their reliability, simplicity, and
ease of operation. Since it’s a replacement to the 53T6, I wouldn’t think it would be a liquid or gas engine because it won’t be used for direct
interception (thus not as agile as a kinetic force weapon), instead exploding near the BM to destroy or disable it. Weaponry/propulsion isn’t my
strongest topic but I’d hazard a guess and say a mix of aluminium powder, nitrated organic (nitroglycerin, nitrocellulose, maybe both?), and a
strong oxidiser like ammonium perchlorate.
In chemistry, sometimes the solution is the problem.
It’s been a while, but I’m not dead! Updated 7/1/2020. Shout out to Aga, we got along well.

The launch and smoke looks very similar to its predecessor Gazelle so I don't think they've changed the motor design much. (Here is a beautiful video
of the old one by the way https://www.youtube.com/watch?v=IVrEYRdYYxQ, note the shock wave as the first stage disintegrates from aerodynamic forces.)
It is a solid rocket, there are simply no liquid fueled rocket motors that can accelerate a rocket at 100-200g. The similar anti-ballistic missile
Sprint used double base composite propellant so ammonium perchlorate, nitrocellulose, nitroglycerin, aluminium and zirconium if wikipedia can be
trusted.
My guess is that the brown smoke from the Russian missile comes from large fractions of metal oxide catalysts (it does look similar to copper
thermite!). This would sacrifice specific impulse for burn speed but since the thrust must be around 10 meganewtons (more than all three space shuttle
engines combined) this is probably the only way.

Does look like Copper (or Manganese?) oxide(s) in the exhaust.
Or Bismuth trioxide? Gives a bit of a brown color to smoke from microstars-

That exhaust color is interesting, brown smoke ? at first i thought it was from the dirt of the ground.
