The K2 would likely be facing the T-90M not some North Korean T-62 derivative. And that is assuming the T-14 won't be available before the K2 enters service in Poland in any decent numbers.
K2 would be facing no such thing as the Russian army is still bogged down in Ukraine.
It will take Atleast a decade for the Red Army to regain its prestige, and that’s assuming massive deep systemic reforms and purging. Stalin style purging.
24 K2 have arrived in Poland with 150 plus on the way based on last know numbers that’s more than the 20 of T14 in Russian inventory. By the Time T14 is available to equip a single regiment of the Red army at this rate the Poles will be deep into building K2PLs with about 700 M1A2 sep3, Leopard 2PL and K2. The Existing T90 fleet for Russia is 200/400 not considering losses to Ukraine and that’s optimistic.
Circumstantial evidence is Russian tank production is lagging behind,
Less than 3 weeks ago Dimitri Medvedev dressed like SS Major Toht (Raiders of the lost Ark) toured the UralVagonZavod tank plant. He came in like Darth Vader landing on the second Death Star. Threatening criminal prosecution to the management if They didn’t meet the Quota of delivery.
How do you say
“The Emperor isn’t as forgiving as I am.” I’m Russian?
Basically T14, T15, Kurganets-25, Boomerang, the 57mm gun, SU57 are the wunderwaffen of Russia. Interesting ideas failed by a crumbling economy, industrial base ambitions beyond resources.
