See, now I know not to post another duplicate of this, lol.

But after reading the DICE post, I picked out a few noteworthy things:
 * 40mm grenade launchers make a return, swapping out one of the medical gadgets (I'm guessing the defib)
 * The heavy barrel attachment for assault rifles makes semi-automatic fire more accurate, but adds recoils in other fire modes (alpha never noted that :/ )
 * Engineers will be able to use RPG's or AA missiles.

That last one made me happy, very Happy. BFP4F is lacking on that on maps like Oman and soon-to-be Dragon Valley.
