Call Of Duty 5 : World At War
Coaxial Machine Gun is a perk in Call of Duty: World at War, which allows the driver to fire a forward mounted machine gun, granting the tank considerable anti-infantry capability. This is not the same as the passenger controlled turret, so don't worry about losing any extra firepower. The machine gun fires at head level in whichever direction the body of the tank is facing, so although the range of motion is limited, it is much more effective against infantry than the tank's main turret, and does not require the driver to switch seats for machine gun access. When the main gun of the tank is facing forward, you CAN in fact aim the machine gun with the crosshairs. This perk is unlocked at level 40.
