Or, in layman terms, the "Silenced Sniper". 1 hit headshots, scope, semi auto but just slightly faster firing than the Scout. Includes pinpoint accuracy
The SVU is already here on modded servers, and takes the place of the G3. No reason to have it, unfortunately.
But the SVU is a T weapon, the G3SG1 is not. it's just a spawned gun like all the others for everyone
