You cannot make tanks without high strength ball bearings which are only made in Sweden and now embargoed.

Perhaps you will explain how the Russians managed to manufacture tens of thousands of battle tanks to fight and defeat the Germans in WW II with no access to Swedish ball bearings, yes?

Perhaps you will explain why russians are gifting so many tanks to Ukrainian farmers? Mostly antique tanks, though.

What the hell are you smoking? Powerful stuff obviously.

That was WWI, this is the 21st century where you imagine the are still using the sort of parts with the same specifications they used 80 years ago? Have you no idea how much more sophisticated T-80s, T90s are over WWII T-34s?

Suggest you finish High School and get back afterward.
