Could you cease regurgitating the NATO sponsored deep throating of the M142 systems please?
Like sure according to twitter glowies, SRBM is now the most difficult thing to intercept, after the whole US military spent ages claiming SCUDs are useless because "they have predictable trajectories".
No, putting a SRBM on a mlrs is not revolutionary, the Russians can put Iskander on theirs, and Ukraine has afaik (I welcome reports to the contrary) failed to intercept even a single Iskander.
The Smerch was designed by the old USSR and has mildly better range using guided rockets vs HIMARS. A recently designed Eastern bloc MLRS like PHL16 completely shits on it, because it can slot IRBMs and not just scud ripoff on top of having better range and accuracy in general.
A strike volume of 10 random storehouses next to the front being blown up in a month isn't a significant military achievement, if so, Russia would have won the war in 1 week with their cunning Iskander attacks on Ukraine storage depots which Ukraine is completely helpless against.
