But this new capability as soon as it is introduced could have repercussions on the ground, when Russia was on the offensive in Donbas in the summer of 2022, the Himars were introduced and attacked several Russian logistical depots and storage, seriously damaging the Russian offensive effort in Donbas.
It's hard to gauge how effective GMLRS strikes were in totality, considering tha Russians were lobbing over 15,000 shells a day during some periods. Though I do concede that GMLRS had a massive impact on the war.
Moreover, while there were some notable strikes, in particular the Wagner HQ, the strike on a building with over 500 men, the reality is that the GMLRS was "game-changing" because it forced the entire Russian Army to adapt, rather than it's physical effect (destruction of enemy assets). Now I haven't served in an army, but I have managed people before. Getting 10 people to learn new warehouse procedures was like pulling teeth. Getting 150,000 men to do so? Can't imagine it.
It's a miracle that the Russian Army adapted as well as it did. Comparatively, adapting to an occasional ballistic missile strike is going to be much less painful. But sure, I won't be surprised to see a high profile attack every few days for the next 3-6 months or so. I just don't think that these "wonder-weapons" are going to significantly alter the current character of this war.
ATACMS with this attack will cripple Russia's ability to use helicopters effectively, forcing them to disperse heavily or more likely, move much further away from the front line, which could have consequential effects on the ground.
I thinky you're really overselling it here. But we'll see. I've been wrong many times before.
