Intellectually, I knew this

But I hadn’t realized that they are so easily gotten to.

How to stop an MRAP. 

Normal truck brakes.

I actually stopped and looked at one the other day, just to check. The police were VERY happy to show it off.

Now you know. I would imagine anything comparable to a .308 or .30-30 would do. A 55 grain 5.56-45 might not, at least not in one shot. But a heavier bullet should.

Now you have a disabled and non-mobile Mrap.

How things progress from there is up to you.

All knowledge is useful at some point.
