HE-111 waist gunner firing his post side 7.92mm MG15 machine gun. High losses during the Polish Campaign lead the Luftwaffe to add two machine guns, one to the port side, other to the starboard side, to give the HE-111 better protection from side attack. But due to limited space, as you can see here, there was only room for one gunner to man both machine guns. If you look under his feet, you can see the ventral machine gunner’s position.
