MIRV and MARV are rather different... MIRV means you might have say 6 or 8 warheads on the warhead bus and the warhead bus has a liquid fuelled rocket so as the warhead bus flys towards the ultimate target it releases warheads on the way which each fall towards targets on the missiles flight path to its ultimate target.
It can hit multiple specific targets but those targets can't just be anywhere... they need to be either side of the flight path of the missile towards its primary target.
Each warhead is released to fall onto their specific target so the bus might change direction in flight to release warheads toward their targets and then manouver back to its original flight path to make sure the last warhead can hit its target too.
With MARV there is no warhead bus, each warhead is its own missile and each one is released and manouvers to hit their designated target.
They are different from what the Russians have because they are more like aircraft than bombs with control surfaces.
The MARV is not intended to evade ABM systems, it is to precisely hit targets that are further apart.
The missiles the Russians use will have sensors and systems built into the warhead to detect interceptors and manouver specifically to evade them which makes them much much harder to intercept.
These MARVs will be rather more difficult to intercept than MRVs (where a missile might have 4-6 warheads that might all just fall around a point target like a city in a random pattern) or MIRVs(where several targets along the flight path of the missile need to be engaged) or MARV (where several point targets need to be hit with precision because they are hard targets.)
Missiles with flight ranges of 3,000km wont be going anywhere near as far as missiles with a range of an ICBM.
S-400 and S-300V4 can engage targets with flight ranges of 3,000km rather easily...
