Historically, the Star Army's predecessor, the Army of Uesureya, maintained at at least 2 or 3 special forces units of about 1000 snipers each. I don't think the Star Army has that many, but there are some Nekovalkyra snipers around, in the sense that there are special forces units where small teams of stealthy infantry nekos sneak behind enemy lines to make precision strikes. I would like to add more detail on that, because right now there's basically no wiki documentation.
