In November 2014, Bellingcat published a report that identified the Buk TELAR (missile launcher) that downed Malaysian Airlines Flight 17 as “Buk 3×2,” originating from Russia’s 53rd Anti-Aircraft Missile Brigade of Kursk. The Buk was called 3×2 due to an obscured middle digit, which was not identifiable at the time of the report’s publication.
