Russia has lost over 100 T-72B3 Obj 2016 tanks out of 570 (in less than three months btw) they got and those are equipped with Thales optics what are most sophisticated Russians have and can't be replaced.
Bzzt. Wrong. I already said it here at least three times. Russia made their own thermal sights using microbolometers to replace the Thales ones in 2016. It took them two years after the 2014 sanctions due to the annexation of Crimea to make that sensor. And in 2017 they got MCT thermal sights working which are one step above that and were never available for import to Russia in the first place.
This is a repeat of the spiel that Russian cruise missiles were supposed to end two months ago because they did not get cruise missile engines from Ukraine anymore. Plus, it is not like the West has exclusive control of thermal sight technology. China also has it. And do they import it from the West? Nope.
They were also strunggling with manufacturing home made optics (worse quality vs Thales) so I don't see how anyone can think Russia will be ready for attrition. Yeah, Russians have a lot of tanks... but most of them are older T-72 and T-80 models without any proper night-combat capabilities while Ukraine is getting that stuff for free.
Ukraine was getting it by paying for it. They have a factory to make thermal sights for the T-64 mod. 2017. The sight used some Western components and was basically a licensed production of US thermal sight technology. It was better than the one the French were supplying to Russia. Yet Ukraine is still losing. Right now Ukraine are getting T-72s from former Czechoslovakia and Poland as replacements for those tanks. The tanks NATO is providing have no thermal sight at all and are in fact worse than the Soviet T-72Bs Ukraine used to have in reserve.
Many writers in this forum live in made up reality where Russia has endless supplies of modern AFV's and capability to produce such weapon en masse. It doesn't have vast Soviet era armies full of men from different republics either... so throwing more men to the grinder isn't an solution because now those guys are Moscovites and other "our boys" not some men from Kazakhtans etc.
Russia is not the Soviet Union but it is a mistake to underestimate the capabilities of their MIC. The amount of cruise missiles they have used in this operation is a good example of that.
The difference is that the Soviet Union was a failing economy when it went into Afghanistan. Russia today is an energy exporter with a solid relationship with China.
Not just that. But the Afghan war was never existential for Russia. This war in Ukraine is. And the Afghan government the Soviets left there only collapsed years after the Soviet Union itself collapsed. The government the US put in Afghanistan didn't even last a single day after they left. In fact it collapsed while they were evacuating. The whole ordeal makes the US evacuation from Vietnam look stellar in comparison.
