The Rebel Soldiers on Hoth protect Echo Base in The Empire Strikes
Back. These use the same torso and helmet as LEGO did, but
with matching waists, legs, and arms (in two different colors).
One wears a white jumpsuit, the other grey. There's no official
job description of either, but it seems as if the grey-suited guys
stay inside the base and work with taun-tauns while the white-suited
guys work as soldiers.
