Russians took out another HIMAR yesterday along with 30 crew members. Now, down to 7.
I imagine that the HIMARS will slowly be taken out just as the 777s are being destroyed. Ultimately, it makes little difference because the focus on these systems has just been hype. They are certainly good, but not all that special and utterly incapable of changing the outcome.
The video from Prague is impressive. That needs to happen all over Europe and here.
