Nothing comes out about them, but they're probably not THAT good.
They do regularly cross train with foreign forces (participated in a Russian lead exercise recently too).

They have really good standardized gear and probably are better trained at certain kinds of operations but tbh, they haven't been in an actual war.
Their effectiveness is up in the air and can't be judged by mere pictures.
Coming back to SSG, I just remembered
