Hoth
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.
