Halo Wars Strategy - Stopping a Warthog Rush with the Brute Chieftain

I was going to record my Brute Chieftain rush strategy, but my opponent tried to pull a warthog rush on me at the same time, so I took him down and we got a Warthog Rush Counter video instead! I noticed the Warthog Rush strategy hosted on Xbox Live and a lot of users using it, so hopefully this will help you all out in countering it better!
This is a real, working counter to a Warthog Rush, as you can see in the video, since the video was recorded straight off Xbox LIVE!
