Ok, this Russian TV analysis is a gleaming pearl of bullshit grown from a single grain of truth. This gets technical, but TLDR: Russian tank guns can also shoot guided missiles for long-range targets… in theory. [1]
So, back in the 1950s & 60s, there was a school that said long-range anti-tank guided missiles (ATGMs) would make tanks obsolete. (Sound familiar?) One bright idea tank designers came up with in response was dual-mode tank cannons that could fire regular shells -or- ATGMs. [2]
You could then fire regular shells against most targets but keep a few more costly, bulkier ATGMs for ultra-long range shots. I -think- that’s what’s happening in this Russian TV analysis, where the T-90s are killing Leopards at extreme range without the Leopards firing back. [3]
