Alla says this aug drops in the mission Delivery. I'm wondering if anyone has seen it in other missions chests. Another question: the aug Blue Sky is obviously the "brawn" part of the lore group Lesser Burning Lands Brains or Brawn. Is there actually an aug for the "brains" part?
I've only seen it in the pof mission, and it was probably just delivery like Allah mentioned. However, in the +100 times I've done delivery (not an exaggeration) I've probably seen it thrice or so. Your best best to get this is to kill the named in mearatas for it.
