What Is the New Symbol Appearing on Russian Military Equipment?

"OSINT Defender reports that the new symbol could be related to Russia's renewed border

offensive in northeast Ukraine. Russian armored assault groups are attempting to breach Ukrainian defenses, particularly around Vovchansk, where Russian forces have been spotted entering the border town.
In conflict zones, symbols like these primarily serve as identification friend or foe (IFF) measures, a way to prevent friendly fire. The most prominent marking has been the 'Z' that appeared on many Russian armored vehicles early after the invasion in 2022 and went on to become something of a symbol for Russians to show support for the war effort. According to Ukrainian officials, Moscow has made "tactically significant gains" in areas of the northeast region, where Kyiv has fewer defenses." MS
