(Okay...i'm trading mine out though, anyone else who wants to should post) the sniper looks up surprised and a shot whizzes by him as he turns the knife plunges into his side and he falls making the wound worse, he bleeds out within seconds(i'm going to assume you loot the body)
A quick search of the body reveals one clip of 30.06 ammo and two multitools
(Sorry wise, i figured sea would have to be up there to loot the body anyway)
"alone huh? sounds like fun, anyway it looks like we are clear of that sniper, but i'm betting it'll be awhile before we get much use"
