someone figure out the Ghost one
The challenge is titled "Ghost Busted" (funny enough). You have to headshot an enemy with an LMG that is wearing the PMC Elite Heavy uniform.
I got it from spraying lead at eye level with LSAT, not very hard for a classified patch.
In every group there is 1 guy, off the wall bonkers but loyal as the best dogthat carries a machine gun and will spray 1000 rounds at a flea [tiniest annoyance] You just met me & my LSAT"Bring the Pain"
