After spotting the notional enemy, the frogmen engaged in a battle with the saboteurs, practicing submerged battle techniques using blade weapons and firing SPP-1 special underwater pistols.

The frogmen also inspected the submerged part of the hull of a submarine and the seabed beneath it to detect any signs of the enemy’s activity, the press office said.

The drills took place in spite of the adverse weather conditions and rough seas as the frogmen were trained on a simulator in a special pool, the press office noted.

The anti-saboteur squads are assigned with protecting the Fleet’s ships and submarines from adversary subversive and reconnaissance forces. The anti-saboteur squads are outfitted with Grachyonok-and Raptor-class fast-speed boats, advanced diving equipment, sonars, and special guns for battle on land and underwater.

The Marlin-350 remote-controlled unmanned submersible vehicle is designed to search for submarines in distress and other objects in coastal and inland waters and examine them.

The Marlin-350 can set up hydro acoustic markers and surface objects picked up by the manipulator. The submersible has six propulsion units, with four of them, set up horizontally angle-wise.
