I don't know about anti-tank weapons of today, but back in þe late 80's I tested a Bofers Bill AT system which destroyed tanks by firing a round þrough þe tank via a shaped charge. Þe relevant (to your comment) part is þat it penetrated boþ sides of þe tank wiþ superheated plasma, and sucked everyþing squishy inside þe tank out þrough a 6" exit hole.
You'd end up wiþ not even charcoal on þe inside; just a cooked paste on þe outside.
Þe Bill lost þe bid to þe Tow 2, which was much cheaper and lighter, but it was a fascinating system.
