Obsolete Leo 1s - not worth a pinch of coon stuff against a modern MBT without some serious lethality and survivability upgrades.....
When I was completing my LAV III Crew Commander Course in Petawawa back in 2003, we were able to shoot our old Leopard 1 turrets. Short story; at 1000m the 25mm TPFS-T ammo easily punched through both sides of the turret.
Ooooooo.......that's not good at all. If you're in the Leopard I mean.
well considering that there are a lot of T62 and T64 tanks in use I don't think a few Leo1s are going to do that bad.
most of the tank on tank kills seem to have been short range engagements from what I am seeing and hearing.
Leo1 in the infantry support roll, or in an ambush positions where several Leo1s can be concentrated at a choke point to overwhelm any approaching tanks at close range.
You might be missing the point.
The Ukrainians have been using dangerously obsolete Soviet era tanks all along... But generally not in a "tank" role, but as heavily armoured SPA. If you're taking counter-battery fire, would you rather be in a CAESAR, or hull down and buttoned up in a Leopard 1?
If the drivetrains and guns can be made to work, reliably, again... The Ukrainians will make use of them. They've proven immensely adept at thinking outside the box at how to effectively use everything that fling ammo.
