Yes, I trained with the the Russian Spetnaz (with their Far East Army in Vladivostock) (see pic)

I think in the post you are talking about, I was talking about the lack of a Non Commissioned Office (NCO) corp in the Russian Army. One of the strengths (and I am biased since I was one) of the US Army is the NCO corp. NCOs get things done, are trained/taught/schooled to think, react, and lead all within the framework of established battle drills, SOPs. To reach SSG, I had to go through two separate NCO schools that helped me with preparing me for the next level and also helped provide me a support group within the cadre and students. Many of the techniques that I learned translated well and prepared me for my post grad MBA as well as my lean 6 sigma black belt certification.

Contrast that to the Russians.. No NCO corp. In terms of responsibilities, I dealt with a Major (a Field Grade Officer) with the Russians who had the same roles and responsibilities as me. Yes, he had 15 years more experience in uniform than I did but in terms of our jobs, we did the same things. It is a highly centralized command system with decisions made by generals in their army that you would have Captains and Lt. Cols making in the field in the US Military. But then again, that's probably not surprising since the Russians are a conscript Army and the ones that I have also been around (like the French and Germans) before were crap. I asked the Spetnaz soldiers why they chose Spetnaz and they said the pay was better, barracks were better and food was better. None of those were "I really wanted to be the best". With my group of guys, we were all "triple volunteers" as Infantry, Airborne, Ranger. It's what we signed up to do before we stepped foot on Ft. Benning.

Tactically, you can see the results of the highly centralized command structure in the war in Ukraine. They have always believed in heavy (and indescriminate) indirect fire power to pummel the opposition and then take advantage of a breach in throw massive waves of troops (via mechanized means) to push deep and create encirclements. Their infantry weapons are also proof of that concept as well with the AK. This is also why they are having supply chain issues given that their tactics require a lot of ordinance and rounds to be shot down range.

I could talk more but not sure which direction to take this. Would be happy to answer questions.
