The thing is, again, a lot of the tech-tree is unique, majorly functional, design changes to Soviet Base vehicles or indigenous vehicles based on Soviet-Era design philospy (atleast until the most modern vehicles which shifted to a NATO-Soviet Mix).
And if we want to talk about copy-paste, atleast Ukraine has more of a claim on these vehicles than many other nations with said copy-paste. They either designed them, built them, or served with them on large scales under the Soviet Army’s/Ukr-SSR’s Banner (depending on the era).
It is entirely uncontroversial to say that Ukraine has far more of a claim on ZSUs, T72s, Mi-24s than the Italian techtree.
But that is off-topic, I want to again re-iterate the make-up of the tree
Indigenous/Not-present/Functionally-Changed & Significant
Current tech tree configuration, it is a work in progress with suggested changes and many honourable mention vehicles not yet included

I probably got something wrong, feel free to correct me.
Doing a quick comparison with Israel, & China, none of the big players to be on the same scale as Ukraine
Israel is a young nation, comparatively, and did not hold a large standing military for many decades/a century as the other nations did.
China may also be considered the same.
This is said in the context that Ukraine only gained independence in 1991.
Although my knowledge of these is not on par so feel free to correct me.
Going rank by rank, upwards, unique vehicles by same parameters as above
