This pack was most likely created by R1chard, one of the Trusty Crowbar Team members. Where did you find this pack? It's obvious for me, that it was created by R1chard. R1chard, by the way, created quite a lot of packs, before joining Trusty Crowbar (most of them were shit, if you ask me)
That's probabably not the whole pack too. The original pack most likely had NPCs and other stuff in it
And why the hell did you called anti-materiel .50 BMG Barrett M82 a 7.62 M24 rifle? You've never seen M82 before?
