In many ways, the smaller scales (1/72nd to even 1/350th) are easier for figure painting.
Just find a good base color (keeping in mind the basic uniform color) and go for it. After that,
maybe use a darker "wash" color to bring out some shadows and you're done.
The key to the smaller scales is "don't try to over do it". Keep it as basic as possible (including the uniforms) or else find a REALLY tiny brush.
