Dear SJ,
Since you view Russian tanks as ‘the same old same old version ‘x’;
I submit this, as proof of the definition of the word ‘new’:
https://en.wikipedia.org/wiki/T-14_Armata
The “new” T-80 was just a rehash of the T-64.
The “new” T-90 was just a rehash of the T-72.
I will grant you that this is their first actually new tank in how many decades?
And only 100 built, as opposed to the thousands of T-90s.
Take a look at the family-lineage of the most of Russian’s “new” front line fighters, as well. They’re almost all extension the the MiG-29 or the Su-27.
