But I doubt that you are studing real hand combat system of russian special forces because it's very cruel type of fighting.
I'd doubt that too. However, that wouldn't really make much difference as you can get bruised (or killed) by applying even the smoothest of all martial arts. And you can also get no bruise at all in a combat with a systema practitioner. Ultimately, a style is not important. As well as a weapon. You can really judge a system when the practitioner is limited to its rules. And that you can't afford in a real combat unless what you're looking for is a [doubtful] "beauty" of the process.

So, to sum it up, there wouldn't be much practical difference in a hand combat between a typically trained Russian or American or African (for that matter) special forces. What would be much more important is, for example, who would discover the other first. Who would wait until the other one is tired and attack then. And so on. The so-called "open hand combat" is so rare between the special forces in real life, that you could probably only see that in a movie.
