Ah! Don't you love the smell of AT-ATs first thing in the morning? No? Oh! Perhaps that's just me. Rebel scum.
Here we get a fabulous schematic depicting the inner workings of an AT-AT Walker. A great guide for those needing to stop and fix one, because such individuals need a break.
Can you imagine what it's like having to hang about outdoors in the snow, on an icy planet like Hoth, trying to persuade your frozen fingers to insert a screwdriver into the requisite socket? Especially when you're wearing a metal stormtrooper, all-in-one suit. Those things seriously conduct the chill. One second it's a broken down Walker, next it's frostbite. Sad.
On the other hand, the AT-AT diagram is equally useful for Rebel Alliance members looking for a great place to aim. At least then no stormtrooper will be worrying about the cold.
There's also a funny Star Wars hoodie, also featuring an AT-AT Walker enjoying a family Christmas.
