(SCP: The Red Lake) GRU-P Sharpshooter - Obtainment, Perks, Viability, Rating, & HTU

Okay, Sniper-Operative-Number-3.5 here........ We don't count PHM as a full one though.
IMO, one of the best event ops thus far, having obnoxiously high DPS that is CONSTANTLY obtainable. Also, free railgun in an operative and you can GET railgun from the Event, too.
Anyway, I think sitting on SW for two brutal matches is worth this sonuva anti-tank rifle, especially for mid-to-lategame players who've got something like Eradicator or Thavin at the ready. Personally, and many other testers would agree, master this first and get the hang of it, cus it is a blast (mainly, when you're blasting heads off).
