Appearances in Battlefield
The XM307 appears in Battlefield: Bad Company and Battlefield: Bad Company 2.

Battlefield: Bad Company
In singleplayer, the XM307 is rarely seen, but it is extensively used by Legionnaire Mercenaries in the final assault on Serdar's Palace in the courtyard in front in the palace. It is also mounted on to Patrol Boats and CAV buggies. It generally kills enemies in a single shot.

In multiplayer, it is seen as a mounted emplacement with a ballistic shield on certain maps such as Oasis, Final Ignition, etc, and on Patrol Boats and CAV buggies. They act similarly to under-barrel grenade launchers, only they're much more effective since it can shoot 5 grenades before overheating. It can also be used effectively against enemy vehicles, dealing a heavy payload before it has to overheat.

Battlefield: Bad Company 2
In singleplayer, it can be rarely found throughout certain missions as an emplacement usually used by the enemy. It is also mounted on Patrol Boats and on CAV buggies.

In multiplayer, it is uniquely found Patrol Boats on the front and back of the boat. It has a small ballistic shield and performs similarly to that of Bad Company.
