I notice that you know absolutely nothing about Ukraine and about (military) equipment
I previously wrote that during the Second World War, the Kharkiv Tank Plant was destroyed
Kyiv Tankovy
Other tractor and tank factories… were evacuated
Material from Wiki
From 1928 to 1931, T-24 tanks were produced; since 1931 — light tanks of the BT series: BT-2; BT-5; BT-7; BT-7M — produced until 1940; from 1933 to 1939 — heavy tanks of the T-35 series.
In 1939, Mikhail Koshkin created the best medium tank of the Second World War, the T-34.
Before the evacuation from Kharkov to Nizhny Tagil, the plant produced a little more than 10,000 tanks of all types.
On October 13, 1943, the remnants of plants No. 183 and No. 75 united in Kharkov were assigned No. 75 by Resolution No. 19676 of the RS.
I am silent about the T-64 and long modifications, as well as the T-80
and T-55
Oh, how inconvenient “unique” tanks are “absent”
The only thing is that the USSR was one country, even in the name you can read that it is a “union” of countries.
But this is beyond the scope of the discussion.
Please read carefully about the fact that the Uralvagonzavod was built on the Powers of the Kharkiv Tank Plant, which “created” other tanks and now produces T-72 and T-90, I’m not talking about lightly armored vehicles.
So what is the “realistic” view then?
Here are my arguments, you can find all available information in open sources.
And writing about the “Polish subtree” is already rude, come on, I see you like that from the USA, so your branch will then be a sub-branch of Britain…
It will also be exactly what you wrote.
I do not want to belittle the merits of armored vehicle designers from other countries of the USSR.
But you did not study the tank history of the USSR writes about the lack of unique equipment.
