There isn’t even such thing as “the spetznaz”. It’s just a generic term in Russian - there’s police спецназ, army спецназ, спецназ GRU. It’s just another case of “spooky foreign word”.

Also still waiting for these dummies to learn OsNaz also exist

As Shrike said, it’s a generic Russian word for special forces, e.g. American TV show S.W.A.T. was aired in Russia under the name Spetsnaz.

It’s an abbreviation of “spetsialnogo naznacheniya” which means “special purpose”, kinda like the English word SpecOps for special operations, but the meaning is closer to the English word “commandoes”.
