The sniper would be holed up on a catwalk on the north side - where broken windows allowed a good field of view on the van and half the area surrounding it. Jason spotted the man crouching behind a crate there that served as a weapon rest, hidden from view from the outside - urban camo clothing, looking a bit too new to be genuine, more like someone dressing down in a hurry who usually wore more sophistcated clothes. He hdn't spotted Jason, yet. But it was just the sniper - some snipers had a spotter as well, someone to watch their target as well as their back... Jason heard more than spotted another man on the catwalk above him, making a round, moving quickly, almost running back to the sniper.
