Microsoft and the U.S. Army have launched the third and final installment of Halo 3 training, this time the focus being on Vehicles. (See Sniper School and Heavy Weapons Training.) As before, we are given a Play & Win Sweepstakes to go along with the training. As of this posting, the official U.S. Army Vehicles Play & Win website has yet to be launched, but you can still enter the sweepstakes by downloading the free gamerpic pack (a free theme is available as well) from Xbox LIVE Marketplace. All of this is building up to the Halo 3 Championship Tournament taking place in April, so be sure to start practicing now.

Since I am at work, I cannot confirm the existence of the new training videos on Xbox LIVE Marketplace, however I’m sure they will be available soon, if they aren’t at the moment.

I’ll be sure to update this post when the official website launches.
