Much like U.S. special operations forces, Russia has its own elite troops that shine during special missions like counterterrorism and hostage rescue.
"Spetsnaz," or special purpose, is an umbrella term for special ops in Russia and other eastern Bloc states. These elite troops traditionally fall under the GRU [intelligence service], FSB [security service], and other ministries, in addition to the traditional military structure.
Regardless, they are the "core of the best trained men the Soviet Union, now the Russian Federation, could produce," according to SOFREP.
In this video, we get a sense of what these troops are capable of. Though it is worth pointing out that this was produced in Russia and isn't exactly an impartial look at this force.
