Defender Rockfowl

At the Fairfax ruins - the stop light intersection, the defender is very likely to step over a mine and kill himself as he fights some nearby NPC raiders. You must hurry and assist him or you won't be able to interact with this guy later in the game. If he survives he will guard Fort Independence on the flyover above the turret.

He carries a minigun (or gatling laser), some ammo, Outcast Power Armor and Fort Independence Access.
