In 1980, The Empire Strikes back introduce a brilliant concept which will remain in the entire saga : the combat walker. Walkers in Star Wars are traditionnally on the Empire or Old Republic side and look always the same as one or two big canons mounted on a number of legs designed to transport them on the battle field. The all thing displays a heavy armour plating. Even if the concept is totally foolish military speaking, it is really amazing in terms of cinematography.
Indeed, the stuff doesn’t hold water tactically. Walkers are slow and too little manoeuvrable. They always show a weak side that -thank the Maker- rebels always forgot to exploit. In short, some good old Star Wars.
I seize the opportuniy of my new diorama review of the battle of Hoth and its famous imperial AT-ATs to show you this article about every single walkers seen in Star Wars movies. You will learn everything about them : their name and function and all the movies where you can see them. Finally you’ll find a link to a Star Wars encyclopedia for more technical details.
