Lewis is also credited with creating the '' grid square '' map system which revolutionized British wartime cartography . This was probably not an Ordnance Survey style grid based on a system of mile or kilometre squaring , but a system based on squares identified by letters and numbers . In the Battle of the Aisne ( September -- October 1914 ) , Lewis squared two copies of a 1:80,000 map , keeping one copy for himself for observing from the air , and giving a second copy to a battery commander with whom he was in wireless communication .

In April 1915 Lewis was appointed to command No. 3 Squadron , operating on the Western Front .

During the early part of the war, the RFC supported the British Army by artillery co-operation and photographic reconnaissance. This work gradually led RFC pilots into aerial battles with German pilots and later in the war included the strafing of enemy infantry and emplacements, the bombing of German military airfields and later the strategic bombing of German industrial and transportation facilities. - The Battle of Britain (German: "die Luftschlacht um England", literally "Air battle for England") was a combat of the Second World War, when the Royal Air Force (RAF) defended the United Kingdom (UK) against the German Air Force (Luftwaffe) attacks from the end of June 1940. It is described as the first major campaign fought entirely by air forces. The British officially recognise its duration as from 10 July until 31 October 1940 that overlaps with the period of large-scale night attacks known as the Blitz, while German historians do not accept this subdivision and regard it as a campaign lasting from July 1940 to June 1941. - The Royal Air Force (RAF) is the United Kingdom's aerial warfare force. Formed towards the end of the First World War on 1 April 1918, it is the oldest independent air force in the world. Following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world.

Ques: Information: - The AKM ("Avtomat Kalashnikova Modernizirovanniy" or "Kalashnikov modernized automatic rifle") is a 7.62mm assault rifle designed by Mikhail Kalashnikov. It is a common modernized variant of the AK-47 rifle developed in the 1940s. - A battle rifle is a military service rifle that fires a full-power rifle cartridge, such as 7.6251mm NATO, 7.6254mmR, 7.92x57mm Mauser, .303 British, or .30-06 Springfield. Compared to assault rifles and their intermediate cartridges, the higher-caliber rounds provide greater power and range, though they have greater weight and produce stronger recoil, making them less than ideal for fully automatic fire. - An intermediate cartridge is a rifle/carbine cartridge that is less powerful than typical full-power battle rifle cartridges, such as the .303 British, 7.6254mmR, 7.9257mm Mauser or .30-06 Springfield, but still has significantly longer effective range than pistol cartridges. As their recoil is significantly reduced compared to high power rifle cartridges, fully automatic rifles firing intermediate cartridges are relatively easy to control. However, even though less powerful than a traditional rifle cartridge, the ballistics are still sufficient for an effective range of , which are the maximum typical engagement ranges in modern combat. This allowed for the development of the assault rifle, a selective fire weapon that is more compact and lighter than rifles that fire full power cartridges. The first intermediate cartridge to see widespread service was the German 7.9233mm Kurz used in the StG 44. Other notable examples include the Soviet 7.6239mm used in the AK-47 and AKM series, and the American 5.5645mm NATO cartridge first used in the M16. - The AK-47, or AK as it is officially known (also known as the Kalashnikov) is a selective-fire (semi-automatic and automatic), gas-operated 7.6239 mm assault rifle, developed in the Soviet Union by Mikhail Kalashnikov. It is officially known in the Soviet documentation as "Avtomat Kalashnikova". - The AK - 103 assault rifle is a derivative of the AK - 74M chambered for the 7.62 39mm M43 round , similar to the older AKM . The AK - 103 can be fitted with a variety of sights , including night vision and telescopic sights , plus a knife - bayonet or a grenade launcher . It uses plastic components whenever possible instead of wood or metal . - An assault rifle is a selective-fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles were first used during World War II. Though Western nations were slow to accept the assault rifle concept after World War II, by the end of the 20th century they had become the standard weapon in most of the world's armies, replacing semi-automatic rifles, battle rifles and sub-machine guns in most roles. Examples include the StG 44, AK-47 and the M16 rifle. Given the information above, choose from the list below the object entity that exhibits the relation 'designer' with the subject 'ak-103'.
