In late September, the Russian army held the “caucasus-2020” strategic campaign exercise. As the largest military exercise of the year, the war scene, force input and application mode of the exercise are closely related to the current security environment of Russia. Although the exercise has been over for some time, its influence still continues to ferment, and Russian media have analyzed the exercise. From September 21 to 26, the “caucasus-2020” strategic campaign exercise was held in some shooting ranges and sea and air areas in the southwest of Russia. A total of 80000 troops and thousands of sets of equipment were invested to deal with a medium-sized local war and simulate non-traditional security threats such as biological and chemical crisis. According to the scenario, the Northern Alliance, where Russia and its allies are located, is subject to containment and blockade by hostile forces from the West and the south. The hostile forces linked up with the political opposition in the Northern Alliance, instigated the “Color Revolution” by means of public opinion war and information war, and gathered anti Russian countries in the region to step up their force deployment in the western and southern directions, trying to make Russia and its regional allies involved in conflicts or fall into passivity from multiple directions. < p > < p > among them, separatist groups supported by external forces appeared in the north Caucasus and conspired to create chaos at home and abroad; in the southwest, a Russian dominated region of a franchise Republic was attacked by the so-called “armed suppression” by foreign government forces and sent out “help” to Russia; the foreign enemies also launched large-scale air strikes against targets in Russia and its allies in the western direction, and Through “agent” war, it provoked conflicts in Russia’s partner countries. At the same time, some big powers took the opportunity to seize Arctic resources, disrupt the international raw material market order, create an international financial crisis, and jointly impose sanctions on Russia, so as to put pressure on the Northern Alliance. The international community has also taken advantage of the situation to expand its influence in Central Asia, the Caucasus and the Middle East. Russia’s national security is facing a complex situation of multi line and multi domain response. According to Russian media, the “caucasus-2020” In the aspect of background scenario, the strategic campaign exercise integrates the “real scenes” of several local wars in the West and south of Russia in recent years, which is the “scene set” of the security environment of Russia in geopolitical events such as Russia Georgia conflict, eastern Ukraine conflict, Syrian military action, etc., and fully evaluates the destructive influence of Western diplomacy, economy, science and technology and cyber warfare on Russia in the war. Similar to the previous strategic campaign exercises, the caucasus-2020 strategic campaign exercise invited allies and partner countries, and the armies of Belarus, Iran, and Armenian attended. From the content of the exercise, the role of allies and partners is more prominent than in the past. < / P > < p > on the one hand, the Russian army draws lessons from the experience of the conflict in the Syrian battlefield and the eastern region of Ukraine, and applies the concept of camp confrontation to the exercise, so as to check and balance the military actions of the west at the gate of Russia or in the core interest area. According to Russian media, in the Middle East, Iran’s role as a “regional partner” has become increasingly prominent, which can hedge against the strategic blockade launched by the West against Russia on the Middle East black sea front line; in Central Asia, the tendency of “leaving Russia” of Azerbaijan supported by the west is becoming increasingly strong, and the territorial disputes with Armenian are constantly escalating, and the risk of “agent” war in the region is high, and the alliance with allies to stabilize Central Asia It’s an election policy. < / P > < p > in the traditional sphere of influence of the CIS, the effectiveness of the integrated joint air defense system that Russia and Belarus have been preparing to build for many years has been tested. During the exercise, the armed forces of the two countries established a unified command system of air defense and vigilance in the southern military region, and used air defense systems such as S-300, S-400 and “armor-s” to intercept the “imaginary enemy” air cluster composed of more than 50 fighters of various types, successfully defeating the large-scale air attack of the “enemy”. Russian media commented that the Russian alliance system with the CIS as the core is of positive significance for expanding Russia’s strategic depth. On the other hand, Russia constantly emphasizes the role of allies and partner countries in military exercises because of its deep consideration of the current realistic security environment. The United States and many European countries have increased sanctions against Belarus on the grounds of “election fraud”, and have made efforts to weaken Russia’s political and military influence on Belarus. According to the report, Russia demonstrated its strength to the west through military exercises, aiming at uniting allies and partner countries to jointly resist external invasion. < / P > < p > as the largest military exercise of the year, “caucasus-2020” has become a window for the Russian army to show its confrontation ability in the southwest campaign direction. The 58th group army completed the emergency deployment in the border area according to the order; the missile unit deployed the “iskander-m” missile system to the mission area 1000 km away through railway transportation; the Black Sea fleet and Caspian Sea Fleet completed the sea assembly deployment of 30 ships of various types, and completed the “illegal armed base” on the opposite shore under the guidance of “haidiao-10” UAV and Mi-35 helicopter ”The Navy’s shore based missiles and artillery units used the “ball” and “bastion” coastal defense anti-ship systems to attack targets at sea. < / P > < p > in the joint air combat and air defense operations, more than 30 tu-22m3, Su-34 and su-24m bombers were deployed to carry out large-scale air strike drills; the army aviation forces of the fourth air defense group army used unguided aerial rockets to launch low altitude penetration attacks on enemy missile launching positions; the airborne troops used the latest parachute landing system for the first time to complete 10 bmd-4m battles The car parachuted behind enemy lines. Russian media commented that during the exercise, the Russian army successfully responded to threats from multiple directions by using military and non military means.
