Conclusion
Based on the above information the Bellingcat MH17 investigation team concludes that at some point in late June vehicles that were part of the June 23rd convoy from the 53rd Anti-Aircraft Missile Brigade separated. Some of these vehicles returned to the 53rd Anti-Aircraft Missile Brigade base in Kursk and joined the July 19th convoy from the base, while at least one other, a Buk missile loader, appears to have left the main convoy and towards the Ukrainian border, close to a separatist-held crossing. As yet, it has not been possible to establish when the June 23rd convoy returned to the 53rd Anti-Aircraft Missile Brigade base in Kursk, or how many units were in the convoy. However, it is clear that at least one Buk missile launcher (3×2) from the June 23rd convoy was inside separatist-controlled territory on July 17th, and 3 days later a video was uploaded showing that the Buk system loader unit was very close to the Ukrainian border. Considering the established time frames, logical routes, and photographic evidence, it is possible that this Buk missile launcher was part of the same June 23rd convoy as “Buk 3×2” and supported it. However, it has not been possible to establish that relationship between the two vehicles.
