Agence France-Presse reported on February 3 that the US Pentagon said on the 3rd that the US $2.2 billion new weapons assistance plan to Ukraine would include a new type of rocket-propelled precision-guided bomb, which could nearly double the scope of Kiev's attack on Russia. Pentagon spokesman Pat Reid said that the new weapons assistance plan includes the "land-launched small-diameter bomb" (GLSDB), which has a range of 150 kilometers and can threaten Russia's positions and warehouses behind the front line. He said: "This will enable them to have a longer range... so that they can carry out actions to defend their country and recover the sovereign territory of Ukraine." GLSDB may enable the Ukrainian army to attack any part of the areas occupied by Russia such as Dunbas, Zaporoge and Kherson, as well as the northern part of Crimea occupied by Russia. This may threaten Russia's important supply lines, arsenals and air bases. Ryder said he did not know how Ukraine intended to use such weapons. GLSDB produced by Boeing and Saab is a gliding rocket with small bombs. Saab said on its website: "The accuracy of GLSDB is very high, and it can hit the target within the radius of the car tire." However, Russian military experts do not seem to believe that GLSDB poses a great threat to the Russian military. TASS reported on February 4 that Russian military experts pointed out that the long-range weapons provided by the United States to the Ukrainian armed forces - the GLSDB with a range of 150 kilometers - would not have a significant impact on the operational tactics of the Russian military in special military operations. Victor Litovkin, military commentator of TASS, said: "There is no doubt that the provision of any weapon will affect the actions of the Russian armed forces, but it is exaggerated to say that the provision of GLSDB will lead to great changes in the operational tactics of the Russian armed forces. The Ukrainian armed forces will not use this ammunition everywhere. Yes, they can fly 150 kilometers, which is very good. But we will deploy our air defense systems slightly away from the front line, and more air defense systems will be deployed in depth to prevent Ammunition hit our position. " This long-range ammunition can be launched by the M142 high mobility rocket system ("Haima Si") or the M270 multi-barrel rocket system. Litovkin pointed out: "You should know that the Ukrainian armed forces will not use all these missiles against the Russian armed forces, but will use them to attack the settlements. Therefore, the problem of protecting the settlements is more serious than the problem of protecting the land positions of the Russian army. Moreover, the Russian army also has a large depth deployment of echelon missile air defense systems." According to reports, At the joint meeting held by the Ukrainian Cabinet and the European Commission on the 2nd, Aleksi Leznikov, Ukraine's defense minister, said that Ukraine does not intend to use long-range missiles against targets in Russia, but the areas considered by the Ukrainian authorities as its territory are not included. Vladimir Karnozov, a military commentator of TASS, also believed that the long-range ammunition provided by the United States to the Ukrainian authorities could not change the nature of special military operations. Karnozov said: "The provision of GLSDB to Ukraine will not change
