Not sure either of those system work against BMs, only S-300/S-400/S-500s really (and S-350 now). Using 'work' in the loosest possible terms.
Buk-M3 still uses SARH, never heard of BM interception using SARH, not without a nuclear warhead anyway. Tor-M2 uses RFCLOS, which isn't really great for anything.
I hate to rain on your parade, but every piece of information in this post is wrong. First, Russia's Buk-M3 uses ARH, while the upgraded older models use SARH, & The Buk has proven to be their best system for dealing with ATACMS for the same reason that The S-300 & S-400 have struggled in that the missiles on The Buk shoot on the way up & the initial elevation angle is adjustable thanks to the launcher, whereas The S-300 & S-400 have arguably the worst possible interceptors for this task. Remember, those larger platforms are designed to take on aircraft by way of larger missiles that are lofted above, before ultimately falling on, their targets, so regardless of their initial speed, they simply lose too much energy to be able to bend/curve downwards in time against ATACMS that are coming straight down at a considerably velocity.
Ironically enough, upgraded Soviet S-75 & S-125 systems/missiles are actually ideal for this "mission" for, well, exactly the same reason as The Buk as, again, both older "antiques" shoot on the way up with the initial elevation angle also being adjustable, & before you laugh, the modern variants of, say, The S-125 from Russia, like The Pantsir, are much more accurate, now, & can intercept targets with a top speed of 1000 m/s, or just under the maximum speed of ATACMS. I could very well be wrong, of course, but for Russia, the challenge of taking down ballistic missiles doesn't stem from the radars or even a lack of "hit-to-kill" technology - you simply need missiles with speed, range, maneuverability, &, crucially, sufficient motor burn times in order to be able to intercept the incoming missile while yours is still under power (I can't do anything about the personnel, LOL). The Buk burns for 15 seconds, there is a version of The S-75 that has an insane kinematic range of 60 kilometers meaning that the booster & motor burn for a combined 50 seconds, which is just nuts, lol, & The S-125 uses a 4 second booster & a 22 second sustainer at 780 m/s. From there, calculating the point of interception, or thereabouts, is just basic math.
Regarding The Tor, RFCLOS is simply command guidance, meaning that, just like The Pantsir (as well as The S-75, S-125, & Osa), the missiles don't have their own seeker heads, but the idea that RFCLOS "isn't really great for anything" is absolute nonsense.
Overall, Russia would do well to implement a kind of Irbis-E upgrade combined with the rotating ability of The S-350 for their S-300 & S-400 systems by adding a second twt, thereby doubling the power & amount of target channels for said platforms while also greatly enhancing sensitivity, & the same should be done with The Pantsir & Tor, except that those engagement radars won't rotate (duh). Even for shortrange systems, only being able to handle three & four simultaneous targets, respectively, isn't even close to being good enough, imo, but get them to 6 & 8 & you're cooking with gas.
Similarly, the current specs of The S-300 & S-400 are pretty good, but they could be so much better. Being able to prosecute 6 concurrent targets with 12 missiles (The S-300) within some field of view that I cannot currently remember was great in The 80s, but now? No, & especially not with TOT strikes that exploit the "blind spots" of such systems which can be at least somewhat addressed by having the engagement radars rotate at 40 rpm as is the case with The S-350. At that point, you would just have to equip those larger platforms with Pantsir & S-125 missiles, among others, for example, to be able to fend off saturation attacks without having to use "the good stuff", if that makes any sense, & the same goes for their shortrange systems, as instead of trying to stop ATACMS solely with the more expensive S-300 & S-400, simply outfit The Pantsir & Tor with their own launchers for S-125 missiles, & the result is that you have just dramatically increased your defensive capability against ATACMS, etc., across the board for practically nothing, as those upgraded S-125 missiles are ridiculously cheap. The setup time isn't great, of course, but this is a much more realistic "solution", which reminds me - The Buk family should at least have an additional launcher.
Okay, that should be everything. Sorry, lol, smh.
