 ATA CMS missiles put Russian air defense in a difficult condition. Following Ukraine's use of recently provided U.S. artillery missiles in long-range attacks of airfields, air defense systems, ammunition facilities and other infrastructure in Russian occupied areas, the Kremlin has now begun conducting simulator missions throughout its air defense forces. The Kiev Post-Media outlet wrote this. It is recalled that on October 17th Ukraine carried out attacks against two airfields in occupied Berdiansk and Luhansk using the M39 cluster munition variant of the U.S. supplied MGM-140 ATA CMS. The attack destroyed or damaged over a dozen Russian helicopters, air defense systems and ammunition dumps at the sites. Russia claimed a second attack using ATA CMS on October 25th against another airfield to the south of the Luhansk region had been foiled with two missiles being shot down. That said, there is mounting evidence that Ukraine's missiles had actually struck a Russian S-400 air defense complex. On October 30th, Ukraine struck a Russian air defense system on the Black Sea in occupied Crimea with a series of combined missile and special forces attacks on the peninsula. Despite Russia's claims to have brought down the missiles during these attacks, it was soon being reported that Moscow's forces were moving logistics and command facilities farther from the front line and out of range of the ATA CMS. It was further announced that air defense units throughout Russia were starting to train on simulators specifically to intercept and destroy ATA CMS. Former deputy commander-in-chief for integrated air defense throughout the CIS Lieutenant General Itek Bizev said combat teams of all air defense weapons in service with the Aero space forces are training on simulators as part of the combat preparation of the entire air defense system across the country. He added that the reason for extending the training beyond those teams deployed for the war in Ukraine was that today Ukraine has ATA CMS missiles and tomorrow they may emerge in borderline and adjacent countries hostile to Russia in the northwestern, southern and other directions.
