Given the environment in which they operate, it is perhaps unsurprising that it is the Naval Spetsnaz who have the most distinctive equipment. They operate both above and below the surface; for the latter they use not just Protei-5 one-man diver propulsion vehicles, but also minisubmarines such as the Piranya (which can carry six operators for some 1500km/930 miles), and the smaller two-man Triton-1.
