“And these 35,000 Kornets have as yet failed to destroy the Ukrainian army.”
Ukraine has not launched an armored assault. They are infantry centric...soon to have a division of mechanized infantry.
The Kornets are of little use against anything besides armored vehicles. And if one of those gets within 5,000yards, kaboom.
The Kornet can take out any tank in the world. Which is no big deal anymore, as there are at least a half dozen cheap ATGMs that can too.
My point is that whatever number of Leopards Ukraine gets, it’s highly unlikely to make a difference considering the scale of hostilities.
Ukraine has long integrated tanks in its brigades - the Ukrainian army has long been a brigade level organization, without permanent higher level units. This is an old criticism, how valid it is I don’t know.
In any case, even Airborne and Naval brigades had a battalion of tanks, and some Mech brigades and the Tank brigades had two. There’s been plenty of occasion for Russians to snipe at Ukrainian armored vehicles.
Ukraine has indeed engaged in armored attacks, notably and very publicly in the attack on the northern part of the Kherson bridgehead on October 2, which was entirely by mechanised forces, and in the Kharkiv offensive. The main exploiting tactic there was for “heavy” tank led units to fix points of resistance while “light” motorised units flanked and bypassed them, establishing roadblocks.
