Leave the Tornado. It is relatively new. And uses a GLONASS corrected rockets from the beginning ranged 120-200km.
Your ass will be heavily spanked again.
Each and any case when either Uragan, or Smerch, would require pinpoint accuracy - they would just use cluster rockets with homing warheads. MOTIVs for anti armor or 9H268 for anti personnel. Those have their own senses, and will just aim on desired target.
If they want to destroy a stationary target, they will just use a thermobaric warhead.
Or just HE ones, as the distribution of the missile valley won't leave anything there anyway.
Or - finally - they can use "new" missiles with GLONASS correction we already witnessed in this war because Russkie have them for the last decade for both 220 and 300mm cal.
The point is that you most probably have no bloody idea about the ammo types they are using, how they work etc.
Long story short, Russie do have everything the newest M270 system rockets can deliver, yet have multiple features the 270s don't have.
And this much more versatile Russian system is being supported by several different types of ballistic missiles or cruise missiles. Something you don't have. Each and any time, you are catching up the Russkies, with a single switch in the early 90s when your rocket artillery get ATACSM and new, longer range rockets, while Russkie liquidated a waste supply of newest tactical missiles and put on hold a modernization projects.
Hyping on M270 Wunderwaffe is stupid.
Ukraine had better systems.
Belarus has.
China has.
South Korea has.
North one either.
Iran has.
India has.
Turkey has.
Everyone who matters has.
The US is so backward, that you can't even get the point what we are talking about, and where is a difference ...
