Page "Infantry fighting vehicle" Paragraph 19

On many IFVs, a coaxial machine gun is mounted on the turret along with the main armament.

The most common calibre is 7. 62 mm (. 30 cal ).

Some vehicles mount more machine guns ; for example on the German Marder, one machine gun fires from the rear of the vehicle, and the Russian BMP-3 has two machine guns mounted in the hull facing forward.
