Bipod

Bipods are an attachment typically reserved for use on light machine guns or sniper rifles. They allow the user to provide more accurate fire from a stabilized position while prone or from a raised surface.

Battlefield 3
In battlefield 3, the Deployable Bipod is an attachment for light machine guns and is featured in both the singleplayer campaign and as an unlockable attachment for the Support Kit in multiplayer. In both modes, the bipod is seen to severely reduce recoil for the weapon operator when deployed, at the expense of very limited mobility as the player cannot move about with it deployed, but can still look around. It greatly aids in providing suppressive fire, which will now give players points for keeping enemies in cover.
