A video of the first combat use of M142 HIMARS systems in Ukraine has appeared. It was posted on Facebook by a volunteer Pavlo Narozhnyi (unfortunately, it is impossible to insert the original video due to his profile settings on Facebook).
The video shows a full volley of two M142 HIMARS units with six missiles each. Each missile in a volley can be aimed at a separate target in a particular sector.
Some people believe that this is the first real use of M142 HIMARS in their entire existence. Some argue that these MLRS were used in Afghanistan and Syria. In any case, this is definitely the first application of HIMARS targeting ruscists. And this is good.
