As you can see, the old 80's AT-AT is far too big compared with the star wars minis. About 1.5 to 1.75 times too big when I measured it. (It's supposed to be around 20 - 25 meters tall). However, the AT-ST looks about right with a stormtrooper beside it, so I think I'll download the rules information for the AT-ST and try playing with it to see what it's like. The AT-ST was a plastic model kit I got at some stage, years ago.
