Orc and Human ranged units

I wonder if anyone could recommend models for orc and human ranged units? To be more specific, I'd like to be able to create races that are entirely made up of these races, and not with conglomerations of other races added in.

I've already considered the Orc Warlock and the hidden wolverine-esque model for the job, and they don't seem to match the feel. Neither really looks like they have any business as serious ranged units.

Humans... just don't seem to have anything whatsoever.

humans you could use the Bandit spearthrower, no ideas for Orcs...

Indeed. I've gotten somewhat satisfactory units for them now.

Can anyone recommend models for a Japanese dojo and a Roman colloseum?
