NATO is donating tanks they don't use and the Leo2's aren't even in Ukraine yet.
So they do not use the Leopard 2s they are going to give away? Hah. As for the Leopard 1s, some countries like Greece still use them and they are in NATO.
Comparing Ukraine with Russia is like comparing apples to oranges. Russia is a superpower that can manufacture NEW tanks all Ukraine can do is upgraded the tanks it inherit during the fall of the Soviet Union and the upgrades are awful just ask Thailand and their Oplot tanks. Russia has lost so many variants of its T-72's in this war that whatever is left in their inventory likely can't be sent to Ukraine and therefor t-55's is likely why they have been taken out of storage. Btw Ukraine has not "produced" new T-64's or T-80's every T-64 and T-80 they use are upgraded ones that were inherited.
So what? The US also only upgrades M1 tanks, they do not make any new ones. Ukraine had thousands of T-64s in storage. The T-64 was not supposed to be any worse than the T-72 which is the main tanks the Russians use. The T-72 was supposed to be the cheap mobilization model of the tank. The US has the Lima Tank "Factory". And Ukraine had two factories upgrading tanks, one in Kharkiv, and another in Lviv. The one in Kharkiv is about as large as the largest one the Russians have.
LazerPig just uploaded a new video hours ago about the Armata and watching it really explains why the Russian army is a mess when it comes to its tank fleet.
He is an idiot.
He seems to think all Russian armored vehicle engines are derivatives of the V-2 in the T-34. For example he claims the engine in the BMP-3 is the same engine, when it is nothing alike, just look at photos of the UTD-29 and V-2 then compare them which other. One is V-12, the other is V-10, and they have different cylinder stroke length dimensions.
He claims the T-95 and Black Eagle prototypes used the same tank chassis with V-12 engine. When the T-95 came with an X-12 engine, and the Black Eagle had a turbine engine. They were also made by different plants, one at Nizhni Tagil, and the other at Omsk.
He also propagates the propaganda that the T-14 broke down in the parade, when there are videos of it rolling out on its own after they disengaged the parking brake in it.
It is pretty well known that the T-14 had issues with the engine and with the control systems design and that is one of the reasons it did not enter service or mass production yet. Heck, I said it here myself. Niznhi Tagil wanted to replace the X-12 engine with a more modern engine they were designing (Chaika) which was supposed to be more efficient and reliable, but when it failed to meet performance characteristics, they had to put the X-12 engine back in.
As for his claim that heavy infantry vehicles make no sense, tell that to the Israelis, who made the Namer and other similar vehicles. As for his claim that it makes no sense to use a heavy tank chassis for an artillery piece, tell that to the Germans, who made the Pzh 2000 based on the Leopard 2 chassis. Or to the Soviets which used the T-80 chassis on the 2S19 Msta artillery. The fact is the heavier chassis provides a more stable firing platform. And using the same chassis simplifies logistics quite a lot. The heavier chassis can also carry more ammo. The 2S19 Msta has 42t weight, the K9 Thunder has 47t weight, the Pzh 2000 has 56t weight. The T-14 Armata is 55t and that is with a tank turret on top. As for engineering vehicles, all engineering vehicles are typically based on an heavy tank chassis. The Germans also have one based on the Leopard 2. Just because the US cannot do it, because they have a fuel guzzling gas turbine on their tank, does not mean the concept does not make sense.
He takes a couple of half truths and spins a narrative.
