Don't know what those two acronyms mean. But going by the the two trailers, it seemed that Finn was a guy in over his head: first shot, first trailer Finn freaks out in the desert, second trailer he's taking off his helmet hyperventilating and then is seen being picked up/saved by Rey. Small sample size for sure, but it didn't look like he was Jedi material. And who knows, maybe he's not and is just picking up a lightsaber cuz he has to. Thought he was merely a deserting storm trooper who joins the good guys.
