I don’t see where Ukraine got these S-300s
The 36D6M1-1 radar, developed by Ukraine’s state-owned Scientific and Production Complex “Iskra,” is a designed to be used in modern automated air defense system and anti-aircraft missile systems.
Here’s what I’ve found on the S-300PMU-2 variant which does nor use 36D6M1-1 radar, unless the Ukrainians substituted it - which would mean that their S-300 version is older, and not the S-300PMU-2.
Unlike the previous S-300PMU-1, the S-300PMU-2 do not use the 36D6 (Tin Shield) and 76N6 (Clam Shell) radars.
S-300PMU-2 radars are:
96L6 all-altitude detector and acquisition radar. The 96L6 works in L-band. It has a 300 km range and very high resolution. The system can detect and track 100 targets. It identifies 4 target classes, including aircraft, helicopters, remotely piloted aerial vehicles, and missiles. It is claimed that this radar can also detect stealthy targets.
64N6E2 3D S-band radar is an upgraded/modernized version of 5N64S (64N6E). It is the most capable radar of the S-300 missile system and has a key role of defeating ballistic missiles and electronic warfare aircraft. This version has a maximum detection range of 600 km. It has 3 400 elements on each side (a total of 7 800), which is a great number for a radar in this band. The system has high resistance against jamming.
Batteries (TELS) also includes the 30N6E2 X-band engagement radar, the 96L6E L-band acquisition radar,
The S-300PMU-2 uses the 48N6E2 missile with a range of 200 km, speed of Mach 6, and altitude ranging from 10 m to up to 28 km. This missile is optimized to engage ballistic missiles for defeating more capable targets, like high speed re-entry vehicles in 35 km altitude, and ballistic missiles with a range of more than 2 000 km
The 9M96E and 9M96E2 missiles with a range of 40 and 120 km respectively. These missiles can engage targets with a maximum speed of Mach 15, capable of engaging cruise missiles, anti-radiation missiles, guided bombs and other precision guided munitions. The 48N6 missiles has single shot kill probability of 80% to 93% for an aerial target, 40% to 85% for cruise missiles and 50% to 77% for theater ballistic missiles. The 9M96 missiles has a single shot kill probability of 70% against Harpoon class missile and 90% against a manned aircraft.

Training against the older variant is better than nothing, but useless against the later variants which are for all practical purposes different systems with different radars and missiles with different capabilities.
