Valid points you’re making. Let me make a counter point: as a German, I’ve seen tanks on 5/6 occasions in my life, never using their own engines. But at the same time, I’ve seen hundreds of cars every day and breathed their emissions. It’s totally fine if tanks continue using diesel, but cars, trucks etc. not using diesel (or gas) engines anymore will have a measurable effect on my health

I actually would also prefer modern stealth tanks battery or hydrogen/fuel cell powered.

Otherwise good point.

But then you'd also lose the capability of making diesel engines for good, and, again, they're not used only for tanks when it comes to warfare.

Just look at the hole the US has dug for itself when it stopped producing civilian sea-ships, nowadays the cost of producing or even repairing its war-oriented sea-ships is way too high. And not only that, but it doesn't have the people with the knowhow to build those ships anymore, no matter the money thrown at the problem.

That doesn't make much sense as military technology typically comes first before any civilian application. Also, it would imply that we should already have lost the capability of making tank tracks as civilian vehicles don't use them.
