If you sent a lone modern tank like a Abrams, Leopard, or black panther back to WW2 with a continuous supply of spare parts, ammo, fuel etc. Would it make a difference?

I know a lone modern fighter jet would make a huge difference but have always wondered about a tank

No

Really?, I was under the impression today’s armor would just tell tanks from that era that their artillery tickles . While their sabat rounds punch through anything . And with modern optics be able to hit targets from 2 miles
