I've yet to see anything on this, and it has me kind of worried. I'm part of a platoon in BF4 as well as an admin, and we have a pretty successful server. Seeing as the whole battlelog thing is going out the window, how would platoons be implemented, if at all? They're a pretty big part of the Battlefield community and I'd hate to see them go in BF1.
My guess is that they might be implemented after the RSP gets admin controls?
