Clean Slate?

Just wondering if there will be a clean slate to wipe everything incl characters you unlock? I messed up a bit and I need it badly but can wait for it... Just so i know it's coming...

I'll do it, if you explain me, what "everything" contains.
(I don't play Ghosts a lot)

The accuracy, the kills, and all that stuff including the squad members you purchase? It will be like I am starting the game from the beginning...
