On February 4, local time, Zelensky arrived at the village of Lobodine, the frontline of Zaporozhye, to visit and express his condolences and encouragement to the soldiers in the trenches. At the same time, he convened a military conference on the front line, where the situation on the battlefield and the protection of critical infrastructure and air defense of the defense industry, as well as about the fighting in Akadiivka and other places. 
And Lobodine is the key position of the Ukrainian army that did not gain much last year, and it is also the forefront of the Ukrainian army in the region.
Zelensky is less than 3 kilometers away from the positions of the Russian army, and the range of the most ordinary mortars can be covered, and its security risks are extremely high. This is of course commonplace for Zelensky, and those Russian fans who still laugh at Zelensky as a drama probably don't dare to imagine that the bunker boy will go deep into the front line. Even if it is an actor, people put their lives into it. What's more, is a taxi driver really more expensive than an actor? 
Previously, in response to the destruction of the large missile boat of the Russian army Ivanovits in Crimea, Zelensky awarded the servicemen of the Ukrainian Intelligence Service with state honors: **2nd degree and ** Bohdan Khmelnytskyi and ** Order of Courage in recognition of their "extraordinary courage" in carrying out special combat missions. 
This kind of Magura V5 unmanned boat, which is very deterrent and lethal to the Russian army, is a semi-submersible surface boat, which is only about 50 cm above the water surface when sailing, with a stealth design and a length of 55 m, 1 m wide5 meters, this volume is at sea, and it is easy to evade the search of the Russian army and radar. 
Capable of carrying 320 kg of explosives to carry out suicide combat missions, the Magura V5 is controlled by radio and air relay satellite communications, etc., and its range of 833 kilometers uses waterjet propulsion and a streamlined hull with a maximum speed of 42 knots, giving it enough time to lurk and attack the Russian army in the Black Sea region**.
Ukrainian Navy spokesman Lieutenant Dmytro Plettenchuk said on a television program on February 3 that now enemy ships are forced to fast in and out from the port of Sevastopol, "hurriedly loading missiles and quickly leaving there so as not to be tracked by Ukrainian positioning." "It is clear that this is to prepare for the blows of Ukrainian unmanned boats and storm shadows.
The missile carrier base of the Russian Federation is located in Sevastopol, although there are other ports on the Black Sea coast, but the main logistics base is this port, where all the infrastructure is located. The most important thing is that Kalibr cruise missiles can only be loaded in Sevastopol, so this is also a place to be watched by Ukraine".
Statistics show that about 20% of the ships of the Russian Black Sea Fleet have been destroyed by the Ukrainian army, and its ability to blockade the Black Sea and carry out "long-range precision strikes" against Ukraine has been greatly weakened.
However, according to Newsweek, Russia's Black Sea Fleet has been paralyzed according to the latest indicators of loss of Russian naval assets.
In the early days of the 2022 invasion by Russian forces, 35 of the approximately 80 seacraft of all types deployed by the Black Sea Fleet provided Russia with long-range strike capabilities and enabled Russia to operate in the annexed Crimean Peninsula and southern parts of Ukraine. 
But now 25 ships of the Black Sea Fleet have been destroyed, and 15 are under long-term repair.
In terms of numbers alone, the Black Sea Fleet has lost half, of course, the loss of tonnage and missile launch capabilities is even greater, and one Moskva submarine alone can withstand several frigates. And Russia's inability to blockade the Black Sea or even withdraw it directly already accounts for the losses of the Black Sea Fleet.
