Actually, here, let me make this just a bit easier for everyone.  Compliments of YouTube and Joe Biden's visit on Don Imus' radio program:

Note, the video covers a lot of other topics, including Obama, Edwards, Clinton (and their run for the White House), along with Attorney General Gonzales, the firings of the U.S. Attorneys and that political witchhunt, and more. Still, pay attention to the video and catch the important part about the MRAP.

If you want to skip most of the video and get to the point, skip to about the half-way point in the video. Just over the half-way mark you'll get the important part of the video related to the MRAP.
