The All Terrain Scout Transport (AT-ST), also known as a Scout Transport, Scout Walker, or derisively as a chicken walker, was a lightweight, bipedal walker used by the ground forces of the Galactic Empire.

Also occasionally stolen by murderbears, though what they did with it afterwards is anyone's guess.

"a giant..." is helpful here as though I trained with plenty of images of person/figure next to walker, sometimes the scale goes wonky.
