Carrier/CMP military demonstration

[Dave Schindel]

This is a long shot, but here goes... A few months ago I came across an old video of some carriers and CMP's going through a demonstration of their abilities. It looked like a display put on for military "higher-ups", and showed the vehicles going over hills and across ruts and doing hard corners etc. I am guessing it was filmed during the war.
I have been unable to find the video again. It may have even been on you tube. If anyone can help me find it or give a link to it, that would be great!
