Actually a better reference on the Ukraine M1A1 SA is here.
It is not anywhere near an M1A2. It is an M1A1-SA (Situational Awareness) with Stabilized Commander’s Weapons Station (SCWS) and gunner’s shields, along with a few other SA mods. It has the same coms and electronics as an M1A2, but that is all.
The best kit for it is the newer Rye Field M1A1-SA Ukraine version.
