The AT-MT (All Terrain Mini Transport) was used for deploying small squads of clones into battle. It had two pilots (sometimes one) and seats for two passengers. Its grey and red markings signified it belonged to the Republic.
Very nice walker! It looks so fearsome. I really like how the color scheme matches your other Republic tank. Great job! BTW, I really like you new main picture! Also, about next summer, I am beginning the production of comic series that follows the exploits of six elite clone troopers. I want to name one of them "Middlehurst", in honor of you, but I feel I ought to ask permission first. Please get me back on that sometime. Thanks! -Dax
