B while bipod is visibly touching something = Bipod (Only usable for weapons with a bipod [duh], some terrain isn't bipodable)

Important things to note:

For guns like the MG42, it's very advised to use bipod. It will reduce the recoil by a lot. If you can't find a suitable place to bipod, burst fire instead of full autoing.

You don't need to hold down RMB to zoom in on binoculars or guns. Just press it once and it will automatically zoom/unzoom in.
