Ukrainian soldiers were accidentally blown up while filming their own BM-21 multiple rocket launcher. During a salvo, one rocket fell out from the rear of the launcher, but it had already been fired, and the propellant exploded. The person taking the video quickly ran away for cover. It may be that this launcher vehicle was not properly maintained, and the device that fixed the rockets in the launch tubes was damaged, leading to this accident.
The Ukrainian military now uses the BM-21 very rarely, mainly because the Soviet-era stockpiles of ammunition have been exhausted, and the West does not produce this 122mm rocket ammunition, resulting in an inability to replenish the ammunition.
