Thank you, I'm well aware of that FAQ's existence. However, I found that one to be slightly ambiguous, and I've even petitioned the author's assistance for clarity. For the record, he admitted in our conversations that even he didn't find every single DG Sniper, and that Chapter 3 was a weak point in his guide. I'm hoping to help him perfect that document once I get some answers.
Thanks for trying. Any other ideas?
