"Lewis" is also one of the earliest aviation machine guns, and it has become the standard weapon for observers/gunners on multi-unit aircraft. Usually, the original rifle butt is replaced by a shovel handle, which is more convenient to shoot targets on the rolling plane. MK2 reduced its weight and became the main forward-fired aircraft gun, equipped with many early fighters. For example, the SE-5A fighter is equipped with Lewis machine guns. When loading, the shooter must stand up, pull the machine gun on the wing back to him, unload the empty drum and install a new one. In the meantime, your legs must firmly clamp the fence. In addition to SE-5A, many British fighters used Lewis machine guns in the1920s.

The British army had a soft spot for Lewis machine guns, which were still used for many years after the end of World War I. Apart from Britain, many countries were equipped with Lewis light machine guns during World War I, such as Australia, France, Norway, Russia, Canada and even the enemy German army. The Germans in the Western Front appreciated the captured Lewis light machine gun very much and thought it was better than Germany's own MG08/ 15 light machine gun. MG08/ 15 is actually an improved version of Ma Keqin MG08 heavy machine gun. The rifle butt and pistol grip are modified, and the tripod is removed and replaced with a bipod. The Germans also compiled a detailed manual for the Lewis light machine gun. During the early days of the Soviet Union 19 18 to 192 1 Civil War, the British provided the White Army with a large number of Lewis light machine guns, and a considerable part of them were seized and used by the Red Army. Soldiers from both sides like this portable machine gun very much.

1938, the British army replaced the Lewis machine gun with the Burun light machine gun. However, after Kolk's retreat, the situation facing Britain was very severe. All shooting weapons were put into use, and a large number of Lewis "enlisted" again. They are mainly used as air defense machine guns, installed on trucks and trains, or as fixed bunkers, among which MK2 aviation machine guns are the main ones. With the mass production of Brun light machine guns in Canada, the production of Brun in Britain has gradually increased. Lewis retreated from the front line again, turned to equip the British volunteers and began to equip armed merchant ships as anti-aircraft machine guns. In many newspapers and photos at that time, we can find information about shooting down German dive bombers or fighter planes. There is always a Lewis machine gun behind a smiling British machine gunner.

Although "Lewis" machine gun was a supporting role in World War II, its life was full of honor and pride!
