Well, one of my ROTC students showed me a sequence from the U.S. army deliberately trying to destroy an Abrams: it took TWO direct hit sabot rounds; two thermite grenades, and the thing still didn't blow up. After another 3-4 direct hits, it finally blew up. I'm suspicious of this.

"lumbering M1-A1 Abrams tank's performance"????

Whatever it is, it is not lumbering. The Adams is rated the fastest tank in the world and its weapons systems can fire while the tank is going at speed.

If there is anything in the world that is "invincible" I'd like to hear about it.
