If you've ever wondered to yourself "Just how tough ids the U.S. M1 Abrams tank?" well we have an answer for you. This thing is a total beast, it's literally a mobile fortress that can take a beating and deal out a beating...Ten fold! This video shows an M1 Abrams rolling over an I.E.D. (Improvised Explosive Device). I think this was suppose to be a car bomb of some kind and it ended up on the side of the road, needless to say the tank made short work of it!
