In Russian the term commonly denotes the special forces of all countries; in English it refers exclusively to the Russian special forces.
In fact, its use in English usually is associated with Russians writing in English or with writers attempting linguistic authenticity. Generally, English-language media refer to them as “Russian special forces.”

Spetsnaz can refer to any elite or special purpose units controlled by the Federal Security Service (FSB) with counter-terrorist and anti-sabotage tasks, Ministry of Interior (police) MVD, and the army special forces controlled by the military intelligence service GRU. Nowadays, the term is used as well to describe any special purpose units or task forces of other ministries (even the Emergency Situations Ministry special rescue unit).

Spetznaz weapons are focused on damage power, rather than accuracy.
