Mk 2 Merk was completely destroyed with the loss of the entire crew when it rolled over a Hez IED, estimated at only 50kg.

Merk2 production stopped about 1989, it is an honest, but obsolete living machine. I'd want to see what a 50kg charge might do to an Abrams.

So, the Merk is by no means immune to IEDs.

What is? It's a question of pounds.

The underside of the hull is identical between the Mk2 and Mk4.

In October 2003, an Abrams rolled over a *150kg* IED created by teaming a Russian anti-tank mine with additional explosives. Two crewmen died, but two survived.
